Richard M. Bohannon cites an M1A1 tank platoon leader from TF 1-37: "Speculation continues concerning what knocked out our four tanks. The three most probable answers are T-72 main gun, dismounted anti-tank missile, or Apache launched Hellfire missile. The fact that Apaches were operating to our rear and witnesses' reports of high round trajectory support the friendly fire theory. However, ballistics reports suggest that 125 mm HEAT rounds produced the damage on some of the tanks. Visual examination of others reveals one obvious sabot hole. Overall, the physical evidence implies that T-72 fire took out our tanks, but the friendly fire possibility cannot be excluded".
