I have recently hit upon the idea of creating armoured infantry in the game as a sort of terror weapon (when I say armoured inf I mean troops in armoured suits like those used in warhammer 40000 etc). I can however not use the SHP I created with these units set up as infantry so I have to use them instead as tanks of a sort and that is troublesome so I was wondering if this could be got around so that they behave like infantry and are classified as such but are harder to kill (no lmg or small weapons deaths etc).
