One idea I had was that the mortar team actually shows its field of fire, much like an MG team. The constant need to re-position because the angle isn't quite right really slows this unit down in a way that dulls its effectiveness.
Don't see how CP 3 Rangers having 3 thompsons and two zooks would make them Riflemen 2.0.
400 MP, 5 men (45 reinforce) with received ac comparable to Pzgrens.
Has cooked frag grenade, Fire Up!, and vet 1 sticky bomb.
Very expensive shock unit with a clear CQC anti-everything role.
I was personally quite happy with Fire Up!'s removal in 2. The suppression changes made for the second game were clearly made to make HMGs more usable later in the game, and I'd favour Fire Up! not returning to keep things that way.
