I think it's out of the question sadly since they removed the zombie army mechanics from the first game.
You know, medics running around collecting wounded and then popping out a new squad.
And without it's recovery function it would make it just a mobile repair bunker.
No, no, no. You don't get it.
I mean IF the recovery option is possible THEN the HT that can repair tanks/vehicules and lay/sweep mines is also possible. So yeah mobile reparing bunker. It reminds me the old Blitzkrieg game series.
I suggest replacing Emergency reparing with a HT that can repair stuff to be a cheaper replacement for Sturmpio squad.
Of course the zombie army mechanic won't happen and i;m not suggesting it at all.
