On April 5, Task Force 1–64 Armor of the US Army’s 3rd Infantry Division, 2nd Brigade, executed a raid, later called the “Thunder Run”, to test remaining Iraqi defenses. The operation began south of Baghdad and went through main roads to the newly secured airport. Iraqi resistance was disorganized, and the unit sustained few casualties. The unit was forced to abandon one tank due to a recoilless rifle or RPG strike in the rear that penetrated a fuel cell and set the engine on fire. The crew was unharmed. Later, the Air Force bombed the tank to destroy it in place, and the Iraqi Information Ministry claimed credit for destroying it.
