This Flak 36 88mm gun is on display at Military Aviation Museum in Virginia Beach, Virginia. Without a doubt the most deadly and effective combined anti-aircraft and anti-tank weapon of World War II. 

Employed in the anti-tank role for the first time by Erwin Rommel during his thrust across France in May of '40, it became a primary means through which he was able to hold numerically-superior allied tank forces in-check through years of fighting in North Africa. 

During the North African campaign, Rommel made the most effective use of the weapon, as he lured tanks of the British Eighth Army into traps by baiting them with apparently retreating German panzers. A mere two flak battalions destroyed 264 British tanks in 1941. Repeated high tank loss from well-placed 8.8 cm Flak guns in the battles of Halfaya Pass earned it the nickname "Hellfire Pass". 

Later in that theater, in the Battle of Faid in Tunisia, Rommel camouflaged many 8.8 cm Flaks (with additional 7.5 cm Pak 40s and 5 cm Pak 38s) in cactus-filled areas. Inexperienced U.S. tankers and commanders rushed into a valley at Faid only to be obliterated. When the U.S. Army's M3 Stuart and M4 Sherman tanks pursued, concealed German guns picked them off at ranges far beyond those of their 37mm and 75 mm guns respectively.
