An anti-personnel device consisting of explosive-laden pipes attached to the side of the tank hull was found to damage the hull upon detonation. Cracks on the inside surface of the hull extending to a maximum depth of 0.4 in. and length of 6 in. were found directly behind and parallel to the anti- personnel device mountings. It is believed that these cracks will lower the resistance to subsequent impacts of armor piercing and high explosive projectiles. Damage to the armored vehicle may possibly be prevented by modifying the device by using a smaller charge or by changing to an explosive of lower brisance.
