Bulldozers to Baghdad

Marine Corps combat D9 dozers in the Iraq War

Marines have always emphasized high-speed mobility. We place a premium on acquiring equipment that is lighter and faster. But sometimes, particularly during military operations on urbanized terrain (MOUT), a “low-speed, high-drag” and “bigger is better” approach makes the best combat sense. Marine infantry need all the assault breaching support they can get. In preparation for the March 2003 drive on Baghdad, I MEF G–3 engineers anticipated and planned for the worst. Sustained MAGTF operations demanded a robust, armored bulldozer capability for congested towns, such as An Nasiriyah, Highway 7, Al Kut, the Diyala River approach, Baghdad, and later Najaf and Fallujah. Known affectionately as the “Teddy Bear” by Israeli and American forces, the Caterpillar D9 (made in the United States, modified in Israel) clearly fit the bill. It provided the Marine Corps and the U.S. Army with a superb 65-ton armored urban assault breaching machine.

During the battle for Fallujah in November 2004, a Marine infantry platoon is pinned down, taking heavy fire from a three-story, cinderblock construction warehouse across the broad street in front of them. An 8-foot wall with heavy iron doors is in front of the structure. Most of the enemy fire is from the roof. The lieutenant quickly ponders how best to get across this killing zone and reduce a tough obstacle and enemy position.

The gunny takes one look at the lieutenant and both nod, thinking and exclaiming the same thing, “Time for Teddy Bears and tanks. Engineers up!” With that, their closest squad leader calls back to one of his NCOs, who further signals behind them down a neighboring alley to their attached combat engineers. A huge Detroit diesel clears its throat, and a friendly, familiar belch of black smoke signals the move forward. As Shakespeare said in King Henry V, “Once more unto the breach.” Sixty-five tons of Caterpillar D9 dozer, reinforced with its thick Israeli armor kit and other combat modifications, moves forward. A second D9 is not far behind, and their operators call for their flank security of two outboard M1 Abrams tanks. Yes, thinks the senior dozer operator, and he says into his radio, “It’s all about supporting Marine infantry ‘at the tip of the spear.’ Without the grunts, we supporting arms are unemployed.”

As the lieutenant feels the ground tremble and vibrate, he sees the huge, familiar dozer silhouette come around the corner. He breathes a sigh of relief, saying confidently to the gunny, “Now that’s assault breaching support.” Like primordial beasts, the dozers lurch forward confidently into the open crossfire. They are focused on the obstacles ahead and the proven Marine Corps version of the old childhood game, “Knock, knock. Who’s there?” Enemy bullets bounce off the D9s as they close the distance. Several rocket propelled grenades (RPGs) prematurely detonate against the field expedient steel mesh barrier encasing the dozer cabs. The M1 tanks on their outboard flanks are faithfully suppressing enemy fire. The Marine infantry add to their own fire with war whoops and hollers of “Go baby,” “Get some,” and “Take that muj” (mujahideen). With momentum and tons of cold steel, the dozers crush their way through the ineffective gated walls and proceed with demolishing the building. Punching out the main load-bearing support columns, the large structure collapses upon itself. Stunned enemy are easily eliminated. Grinning from ear to ear, the gunny turns to the lieutenant and sums up what they’ve just witnessed, “No wonder Israeli grunts call that machine ‘The Zionist Monster.’”

Since 1902, when Benjamin Holt invented the first bulldozer in Stockton, CA, it has been a distinctive symbol of our “can do” American nature. And this cultural icon applied to our wars. Reflecting on lessons from World War II, Marine Gen Holland M. “Howlin Mad” Smith, the indomitable architect of American amphibious operations, focused on this machine. In his classic 1948 memoir, Coral and Brass (Charles Scribners & Sons, 1949) he stated:

Often, the bulldozer was well ahead of the combat troops, and developed a rugged personality all its own. The roar of the bulldozer as it tore up palm trees and dug out rocks was as familiar as the noise of gunfire. The bulldozer became a symbol of American efficiency.

Dozers continued to contribute to American war efforts in Korea and Vietnam, and no one paid closer attention to these combat mobility lessons than the Israel Defence Force (IDF).

In spring 1984, LTC Eitan Lidor, of the IDF’s Hadassah Kravit (Combat Engineer Corps), visited 1st Combat Engineer Battalion (1st CEB), 1st MarDiv. A battalion commander and combat veteran (1973 Yom Kippur War and 1982 Operation PEACE FOR GALILEE), Lidor spent time observing and critiquing Marine Corps mechanized assault obstacle breaching exercises by 1st, 5th, and 7th Marines, reinforced by 1st CEB, 1st Tank, and 1st Assault Amphibious Vehicle Battalion. This led to further contacts and friendships. Other liaison exchanges followed. In 1987 I participated in combat exercises at the IDF engineer base at Ado Reem, in the Judean Desert near Hebron. In 1990 Marine Corps reps from Quantico visited Tel Aviv, where now-GEN Lidor (commander of the IDF Engineer Corps) greased the skids for Marine acquisition of Israeli assault breaching gear. By 1991 this equipment was in high demand by U.S. coalition forces in Saudi Arabia focused on liberating Kuwait. The results spoke for themselves when GEN Norman Schwarzkopf made his famous post-DESERT STORM speech praising Marine Corps assault breaching prowess.

A new piece of gear entered the IDF table of organization in the 1990s. Quantities of U.S. commercial Caterpillar D9 bulldozers rolled off the assembly line in Peoria, IL, and were transferred to Tel Aviv for significant modifications by Israel Aircraft Industry’s Ramta Division. Added to the original 50-ton dozer were 15 tons of armor, ballistic glass, machineguns, smoke grenade dischargers, radios, and a two-man crew configuration. To IDF combat engineers, the D9 became something special. First referred to in Hebrew as “Dov” (Bear), this morphed into the more affectionate nickname “Dubi” (Teddy Bear). This would be the same term of endearment used by Marines in Operation IRAQI FREEDOM.

By summer 2002, I MEF held its MEF exercise, focusing on the situation in Iraq. The Marine mission was to “head up the middle” between the Tigris and Euphrates Rivers from Kuwait to Baghdad, some 500 kilometers up the historic Mesopotamian plain. Main concern to the MEF G–3 engineers was the terrain—lots of rivers (Euphrates, Saddam Canal, Tigris, and Diyala) and congested urban areas. The MEF needed some special capabilities. The MEF’s Engineer Equipment Shortfall Board was familiar with and recommended the D9. The MEF commanding general (CG) (then-LtGen James T. Conway) agreed. Thus the Marine Corps again turned to the IDF for unique assault breaching combat engineer gear. The U.S. Army also identified a similar need. Efforts to obtain IDF D9s were consolidated, resulting in the delivery of nine vehicles to Kuwait in February 2003. Four of these, together with Army heavy equipment transporters (HETs), were delivered to 1st MarDiv’s CEB (combined 1st and 2d CEBs, commanded by then-LtCol Mike Micucci). For ease of tracking and because of their special nature, the four Marine Corps D9s were named “Golda” (for Israel’s historic prime minister), “Ziva” (after the wife of GEN Lidor, who had graciously hosted Marine engineers in Israel), “Matilda” (from the song of 1st MarDiv), and “Natasha” (John Wayne’s World War II dozer in The Fighting Seabees and a tribute to the I MEG’s SeaBees).

Coiled like a cobra on the northern Kuwait border facing Iraq, the Americans and British were ready. The Navy SeaBees of the MEG gathered an unprecedented 54 bulldozers just north of 1st MarDiv’s Camp Matilda. Their primary focus was crossing the line of departure on 20 March 2003. Their mission was breaching operations and rapid mobility. Mounted on sturdy Army HETs that could handle rough terrain, the four Marine Corps D9s had a definite mobility advantage. The MEG’s 54 SeaBee dozers, together with 12 Marine D7s, would, in the weeks to come, provide essential combat and combat service support to 1st MarDiv and Task Force (TF) Tarawa. But it was the four D9s that were continuously at the tip of the spear. It was TF Tarawa that first put a D9 to the real test at the battle of Nasiriyah in late March 2003. Then-MajGen James N. Mattis (CG, 1st MarDiv) loaned Matilda to BGen Richard F. Natonski (CG, TF Tarawa) under one condition, “That you use her to crush as many of these worst excuses for men and SOBs as possible.” This Matilda proceeded to do so under enemy fire as she cleared obstacles all over Nasiriyah. Natonski recognized her exemplary performance over evening video teleconferences, as Matilda provided crucial support to TF Tarawa all the way north up Highway 7 to Al Kut. The three D9s with 1st MarDiv rapidly advanced northwest up Highway 1 to the Numaniyah crossing of the Tigris River. In early April at the final Baghdad river obstacle on the Diyala River, enemy engineers blew key bridges. The D9s were brought up under enemy fire to cut approaches for the 8th Engineer Support Battalion assault bridging units of 1st MarDiv.

The D9s proved their worth to both the Marine Corps and the U.S. Army in the drive on Baghdad. LtCol Micucci stated, “The D9 was my ‘go to’  piece of heavy equipment. It was always there with the faithful HETs, ready and waiting to make things happen.” The U.S. Army agreed and ordered seven more D9s from Israel. They arrived during fall 2003, making a total of 16 coalition D9s in Iraq. All would later be needed.

By 2004 some valuable lessons learned from prior employment of D9s had been lost. Newly arrived staff officers within the coalition simply looked at the assault breaching Teddy Bear as “just another bulldozer.” D9s were scattered “out west” all over Al Anbar Province to the Syrian and Jordanian borders. Little maintenance was done on them, and specialized operator training was nil. The D9 needs a combat operator, not just a driver! This changed in August 2004 with the return rotation of the original I MEF G–3 engineers. By late summer, all Marine Corps D9s were being consolidated at Camp Fallujah. Israeli-based MOUT tactics, techniques, and procedures (TTP) were developed. D9 lessons were also learned during the September 2004 battle for Najaf.

In preparation for the upcoming battle of Fallujah, new assault breach training became a priority. High-intensity combat was coming. The D9 was not a simple dozer or surgical instrument. It was a big sledgehammer meant for a combined arms team. More D9s and HETs were needed, so the Marines asked the theater Army engineers for assistance. This was graciously provided by the Army 420th, and later, 20th Engineer Brigades out of Camp Victory, Baghdad.

Maintenance and repair of the D9 dozers, which were not in the regular U.S. inventory, was a challenge. Caterpillar repair technicians and links with Israeli friends were essential. In combat conditions, “selective interchange” of parts (i.e., cannibalization) took place between D9s.

The real Achilles’ heel of the D9 dozer was transportation. Without dedicated Army HET tractors, trailers, and operators, the Teddy Bears could not be moved. Getting these behemoths into the fight at Najaf took far too long. As MAJ Richard S. Takishita, the Army Multinational Coalition Forces-Iraq (MNC-I) C–7 (engineer plans) officer noted, “What should have been a twelve hour shuttle operation to Najaf took six days. Satisfying the call ‘engineers up’ had to be measured in minutes, not hours or days.” These mistakes could not be repeated at Fallujah.

The buildup for the long anticipated second battle for Fallujah had begun. Fallujah was roughly the size of Tampa, FL. Four Marine D9s were simply not enough. The senior Marine combat engineer colonel in Baghdad thus made his best case to the senior Army engineer general in Iraq. The Marines asked that 12 D9s be consolidated at Camp Fallujah, the main staging area for the upcoming battle. This meant giving up Army D9s to the Marines. This was a tough call for the Army, as their division major subordinate commanders did not want to relinquish this capability. But the Army C–7 engineer at Camp Victory, BG Robert A. Pollmann, backed by his Deputy, COL Joseph E. Chesnut, did the right thing. They even went a step further by offering the Marine Corps all of the 16 D9s in the Iraq theater. The senior Australian engineer at Camp Victory, COL Phillip Van Der Moezel, reminded the C–7 staff of the brutal lessons of Stalingrad in World War II, Hue City in 1968, and Grozny in 1994, 1996, and 2000. Pollmann added, “I’m giving you Marines all the D9s because I know you will use them to win.” With this outstanding support from the Army community, 12 D9s were consolidated at Camp Fallujah, while 4 reserve D9s were prepositioned on HETs at Camp Victory. On the eve of battle, heavy maintenance was performed on the D9s. Pollmann and Chesnut served notice throughout coalition forces that these D9s were no longer “bulldozers”  but “urban assault breaching machines.” All other theater engineer bulldozer missions were assigned to standard D7s and D8s.

Extensive coordination took place as the MEF engineer at Camp Victory, Baghdad, channeled these D9s from all over Iraq to Camp Fallujah. It was not simply the challenge of obtaining the D9s but also of coordinating the HETs, maintenance, convoy protection, and operational security. At MNC-I Headquarters, LTC Art Free, U.S. Army engineers, and his Australian engineer deputy MAJ Joel Dooley, made sure this happened. Senior coalition headquarters in Baghdad did not want all of the theater D9s tipping off the enemy by descending at once upon Fallujah. They were brought in one and two at a time, where the MEF G–3 engineers established what became known as the I MEF “Assault Breaching Heavy Equipment School.”

In organizing for combat, the D9s followed closely the TTP shared by the IDF. Each D9 had a two-man crew; both qualified as operators, but with the second Marine focused as an assistant driver, communicator, and gunner. The dozers were to be employed in teams of two with flanking support from a section of M1 Abrams tanks; Marine infantry covered both. Combined arms support teams, breaching teams, and assault teams repeatedly exercised together. Engineers, tankers, and infantry continuously rehearsed together. A “combat town” area (including buildings to be demolished) was established near Camp Fallujah. Specific techniques in collapsing buildings were rehearsed, as were recovery operations by other D9s, M1 tanks, and M88 recovery vehicles. Field expedient improvements were implemented regarding communications, survivability, and mobility. Brilliantly customized 4-inch series square HESCO (Highland Exchange Service Cooperative of Britain) bastion steel cages were added to an angle iron frame around the cab of each D–9. With its standoff distance, this predetonated enemy RPGs. This innovative idea came from two Marine engineer SNCOs from Company C, 2d CEB, GySgt Earl W. Buckles of Sunbury, PA, and SSgt Ronald S. Gillaspie of Crown Point, IN. It worked in combat. Despite multiple enemy RPG hits during the battle of Fallujah, not one D9 operator was lost or one cab penetrated.

Each D9 was given a Marine combat name. To the original Golda, Ziva, Matilda, and Natasha were added a dozen more. Most were given roguish names by their Marine crews—“Lurch,” “Critter,” “Homewrecker,” “Gladiator,” “Scarface,” “Blitzkrieg,” “Apocalypse,” “Wolverine,” and “Earth Pig.” The four “ladies” in the Marine D9 reserve were “Julie,” “Joyce,” “Lynn,” and “Malinda.”

Capt James L. Zepko, the 1st MarDiv engineer, published a concise operational combat engineer plan for the infantry covering D9 tactical use. This was coordinated with pre-Fallujah Operation GRIZZLY and Operation QUEENS FEINT, devised to shape the battlefield by drawing the enemy prematurely into aerial and artillery kill zones. These worked as planned.

On the eve of the battle for Fallujah, two young D9 Marine operators exemplified the pride and motivation they had being Teddy Bear operators. When asked how they felt about taking the D9 into combat, LCpl James Denby, 2d CEB, of Rock Hill, SC, stated, “It feels pretty good. There’s not much that can stop it.” LCpl Daniel B. Gadd III, 2d CEB, shared this, “If anything gets in the way, my D9 will destroy it.” These Marines were primed.

The initial signal for the D9s to move out and attack south into Fallujah was initiated by mine-clearing line charges and joint direct attack munitions—big bangs. The intense tactical pattern over the next month of combat would be the same. Marine infantry moved forward identifying and engaging the enemy. Tanks and D9s were called up to deal with specific enemy strongpoints. Time and again D9s burst through walls to allow infantry the opportunity to safely enter a building at a point of Marine choosing. Enemy improvised explosive devices (IEDs) and most boobytraps were thus avoided, and the enemy within the structure was caught off guard. In one case a D9 penetrated a building and was directly confronted by the enemy. The dozer crushed them while the assistant driver hit them with automatic weapons fire. An enemy RPG detonated harmlessly against the D9.

Unmanned aircraft systems, such as the ScanEagle, documented the precision of these 1st MarDiv combat operations. As the two regimental combat teams (RCTs) (RCT–1 in the west and RCT–7 in the east) fought their way south, photos showed that D9s and M1 tanks stuck together in their predesignated sections and helped Marine infantry reduce Fallujah one block at a time. Throughout this methodical move southward, both of the RCT engineers, Capt Frederick W. Russell III, (Company B, 2d CEB, RCT–1) and Capt Georges T. Egli, (Company C, 2d CEB, RCT–7), did a masterful job of coordinating D9 assets where most needed. As Capt Russell later stated, “We had the D9s everywhere in the city.”

The tank company commander in RCT–1 was Capt Robert J. Bodisch, Company C, 2d Tank Battalion. His tanks were attached to 3d Battalion, 5th Marines (3/5) and 3/1. He stated that without question the D9 became the engineer equipment of choice over the armored D7 and M9 armored combat excavator. The infantry preferred the D9s for support because they could reduce the largest enemy structures in the shortest time and withstand small arms fire. This was particularly appreciated in the area known to Marines as “Queens,” where Capt Bodisch stated that the D9 was the only equipment capable of leveling enemy reinforced concrete structures.

The D9 Scarface saw a lot of action similar to other D9s. Detonating a “daisy chain” series of IEDs as it cleared a breach for RCT–7, the call from the supported platoon commander was repeated, “Scarface, are you okay? Are you okay? I saw you disappear in the explosion, and I thought you were wasted.” Chuckling, the crew calmly responded, “Sir, we are fine. Things are good.” Later in the battle, Scarface got the call from 1/8, “We need a hole in that wall!” Two Marines were casualties inside a building, and their squad was attempting to get them out. Scarface opened up the front of the building, and the Marines were successfully extricated. As the grunts pulled out, the squad leader told Scarface, “Make it a parking lot!” Scarface tore through to the far side of the building, collapsing it. This forced the enemy to flee outside where they were cut down by Marine infantry.

By the conclusion of the battle for Fallujah, many D9s were “down” mechanically (at least 7 of the 12 committed to action) due to the simple fact that the supply system could not get replacement fan belts. Iraqi debris ate fan belts. As one mechanic from Company C, 2d CEB stated, “There are not many places in Iraq that carry 106-inch fan belts and deliver to a frontline battlefield. And once your fan belt goes out, you are left with a 65-ton D9 paperweight.” Through Herculean efforts, Marine Corps mechanics were able to keep at least the remaining seven D9s running. Multiple tight strands of communications wire served as expedient fan belts. This was crucial, as infantry units were constantly requesting the Teddy Bears.

The D9 proved itself to be a robust piece of combat gear. Despite extensive use in horrible combat conditions with minimal maintenance, the Teddy Bears and their crews did their job. They faithfully responded to their fellow infantry and tank brethren who repeatedly called for them, “Engineers up.”

In January 2005, following the battle for Fallujah, MajGen Natonski, a D9 fan since he commanded TF Tarawa in 2003, stated:

The D9 dozer was a critical asset during the battle for Fallujah. Often at the point of our armored maneuver elements, it breached railroad berms, minefields, IEDs, cleared other obstacles, and collapsed countless buildings containing enemy insurgent positions. The D9 helped facilitate our attack and save the lives of our Marines and soldiers on the Fallujah urban battlefield.

The future of the D9 Teddy Bear dozer is uncertain in the Marine Corps. Those infantry, tankers, and combat engineers who have seen it in action love it. But its future will be up to others. As Marine operations focus increasingly on urban/MOUT environments, there will be a corresponding need for an urban assault breaching machine. Much like the M1 tank, when Marine infantry need a D9 dozer, nothing else will do. Col William F. Hatton, the I MEF engineer, reflected in January 2005:

Toward the end of the battle of Fallu-jah, there was considerable interest at high levels to get into the city and start reconstruction. Focus was on cleaning up and removing large amounts of debris. During one MEF staff meeting, the question was asked by the commanding general as to why the mighty D9 bulldozers could not be directed to this huge task of rubble removal. Without hesitating, LtCol Todd Kaminski, the G–3 engineer operations officer stated, ‘Sir, the D9s are not clearing rear area rubble because they are still involved in forward combat operations creating rubble.’

A toast to the venerable combat D9 Teddy Bear armored bulldozer. God bless our Marine infantry and the combat engineers who support them.
