after it was found that the commander and cargo hatch positions were extremely exposed, and hence the commander and troops were vulnerable to enemy fire, south vietnamese engineers thought out a simple and cheap remedy to this problem: initially, field expedient shields and mounts were made from sunken ships, but this was soft metal and could be penetrated by small arms fire. then armor plate from scrapped armored vehicles was used; this worked well, and by the end of 1964 all arvn acavs were equipped with gun shields. for the u.s. army, acav sets were produced industrially in okinawa for the machine gun, and rear aft and starboard m60 machine gun positions. finally, the arvn's acav modifications were adopted by the u.s. army in vietnam, and by 1965 the full acav set was mass-produced in the u.s. the kit included shields and circular turret armor for the commander's m2 12.7 mm machine gun, and two additional 7.62 mm m60 machine guns, again with shields, fitted on either side of the top cargo hatch. this kit could be retrofitted to any m113. acav sets were sometimes fitted to the m106 mortar carrier, but the different rear hatch found on this vehicle required the left m60 machine gun to be fitted to the extreme rear instead of the side. many kits were added in the field, but at least in the case of the 11th armored cavalry regiment, the vehicles had their acav sets installed in the u.s. prior to their deployment to vietnam in 1966 from fort meade, maryland. additional armor in the form of a mine protective kit under the hull was also frequently fitted.
