Many of the Luftwaffe's aces racked up their impressive kill counts in the Fw 190 A due to its impressive fire power, excellent low to medium altitude performance, durability, and ease of flying. It saw action on both the eastern and western fronts where it was both respected and feared by allied pilots. Armament included two fuselage-mounted 13mm MG 131 machine guns and four wing-mounted MG 151/20E 20mm cannons. The Anton could also be loaded with unguided rockets and bombs.
