447th AAQA Battalion US Army, Belgium, 1945. The M16 was the standard US Army light antiaircraft vehicle used following the Normandy invasion with every armored division having an AAA Weapons Company with eight M16s. These units were often used to protect key sites dumps from enemy air attack. By the end of the war the general absence of the Luftwaffe meant that these M16s could be used in a ground support role, where they earned the nickname åÎÌÇÌ_å±meat-choppersåÎÌÇÌ_åÂ.
