I was always amused by the description of the Rangers - specialists of precise sniper combat, without sniper guns. May be an M1C/D as an alternative for the Rangers would be nice. In general, the Rangers are units of close reconnaissance and sabotage, so they must be an analogue of the German Jaegers or Stormtroopers: they appear from a neutral building to have camouflage and diversion abilities. Because in the current state it is 5 people Paratrooper clones with the simultaneous possibility of having the Thompsons and Bazookas.
I've always thought they should spawn with a beefier Garand (maybe 10 damage and better accuracy at all ranges) compared to riflemen, and good enough that the thompson upgrade is a considerable sacrifice of long range dps.
As it is them spawning with carbines is silly, and even sillier since said carbines are identical to the paratrooper ones. The carbine itself is superior to the Garand for whatever reason, except at very long range.
But as far as rangers exist now idk about giving them any abilities. Maybe sprint would be nice. Other than that I think they're fine.
