What exactly is 'disruption level' - no such term. Perhaps you mean suppression, or are you meaning damage?

In special battles, no repair is made - any damage is carried over.

A rifle section with 50+% damage will automatically receive 10 points of suppression at move start, which you will have to rally away to move them usually. Other damaged units will also gain suppression, depending on morale and experience. Vehicles with track damage will tend to gain suppression as well.

Damaged helos should run off the map, fairly immediately - any damage to air units is instant RTB. A damaged helicopter should be held off the map for the special (or any other) battle, and if it is being presented for the player to use then it is a bug most likely.
