DEFA F1 (90 mm)
DEFA CN90F1, also known as DEFA 921, is a French light gun designed for light vehicles. Operating on low pressure and being exceptionally lightweight by itself, it made the creation of AML-90 possible: gun was relatively easy to operate while also permitted the 5-tonne chassis to punch well above its weight.
The most troubling thing was the long range performance of the gun. Using low velocity ammunition and having rather inadequate fire control systems, the accuracy of the gun was far from perfect if not outright terrible. The Six-Day war and South African Border War, where the vehicles equipped with it were used confirmed it, as the AMLs were being constantly outranged while fighting M48s and even T-34-85s. The light chassis used to accommodate the gun was also not allowing to fire on the move out of fear of overstraining the suspension and transmission (apart from that, the gun was never equipped with stabiliser).
Nonetheless, in conflicts where it was used, it proved to be perfectly capable of destroying MBTs, especially when attacking in flanking manoeuvres.
