Perhaps it would be easier to give all factions a infantry and a tank mine. Ostheer style (except without those goddamn signs which tells people where the mines are.
It helped me saving lots of units because I wanted to flank a squad but I noticed the signs quickly enough.
That would be nice. I've always wondered what relic was thinking with those freaking signs. Maybe because the S-mines cover so much ground compared t other mines. Either way it's a terrible design to have signs announcing mine presence to the enemy.
