True, but then were these part of the Chally 3 update or already fitted to the Chally 2 and if, not would it not be prudent to look at what is shown to work and modify if needed before they cut steel to allow for it, they may well have jamming for missiles, but for a grenade dropped from above?
The Germans incidentally late war added steel plates on legs over vunerable areas on the engine decks such as intakes or cooling grills to protect them from aerial attacks, so its nothing new..
