I had the Idea for the Ostheer to have a ability of a medikit for all inf and supporting troops (including paks and mortars). It would be a free ability so no costs but a cool down time like russians have and the troops maybe could be unable to move and shoot while healing, because i think its not logic for troops to run in battle while beeing injured. Maybe they could also have a mobile Medic Tent, it would cost 3 - 5 pop and would be recruted from HQ, for example. It would be a 3 men squad of medics. They can heal units on the way pios heal tanks, so only 1 squad at the time. The set up tent has to be set down before moving, but could have the option of gathering wounded soldiers, healing in a small range around tent (could work over a cool down ability) and 1 squad could move in the built up tent. In the tent faster Heal rate, but low fire rate and accurancy for troops shoting out of the tent.
