Why nobody touches commandos from UK? Their wiping potential is huge. Thry can equip at weapons and have lots of abilities including demos, retreat with smoke, powerful gammons, are larger squads and also get first strike bonuses. I don't see much difference here.
Long range dps is the difference. Retreat from bayonet range and commandos arnt going to wipe you. Retreat from falls an you are getting equally fucked by every bullet.
