use him in green cover in CQB vs volks, weapon crews and even half-health grens. Avoid group of 2 or more squads and MP44\LMG. BTW really no reason to vet him, usually he die from tank shots only and vet cant help.
he does not die from tank shots.
every time i fight a us officer i direct hit him about 3 times per game and at the end hes still alive.
