Canada thought there was no need for MBT and was going the same route as FRES UV then they went to Afghanistan and found there existing LAVIII (same family as the chosen FRES UV ) was getting opened up by IEDs and also getting stuck in mud. So they ended up borrowing 20 leopard 2 from germany and airlifted to Afghanistan using C-17 and russian aircraft, and buying 100 surplus leopard 2 from the dutch.
US Apaches in iraq was forced to abandon there attack when beaten back by RPG and AK47, the US marines Cobra has enjoyed more success because they were used with troops on the ground.
