As far as I know, Ostheer has only one non doctrinal option for healing, through medic upgraded sturmpioneers. For the army support there is a supply drop, for the army fortress there is passive healing in territories, but for the elite army troops, what are the options? I looked around but couldn't find a way to heal my troops, and have to rely on upgraded sturmpioneer squad to heal. It's actually awesome way to heal troops but is that the only non-doctrinal healing that ostheer has?
