Rules Question

My friend plays Germany, when we play he always takes half his forces as half tracks and assigns them to all his infantry squads as transport. Because of this, when we deploy half our forces at the start of the game he always chooses to deploy all his half tracks immediately with all his infantry inside, telling me that he can do this because he is only technically deploying half his forces and it doesn’t matter that they are all full of infantry squads

Basically, is he allowed to deploy his entire German force at the very start of the game by choosing to deploy only his half tracks that just happen to have the rest of his forces inside them?
