Let's cause some problem for US air force! This small and light aircraft forced US air force to arm F-4 Phantoms with internal cannons (yeah they did not have that when they first entered the war) not only that...problems that F-4s had against MIG-21s during war finally resulted to retirement of F-4s and development of F-15 and F-16
MIG-21 with Vietnamese camouflage, a few fixes on the model and better animations and stronger armaments
