It is good compared to what? On the allied side they are only better than IS, Cons can literally brute force a win by swarming, Penal are straight up better early on, both can be backed up by a sniper vs OST or car vs OKW while having access to being Soviet. Pathfinders can also use the ambulance so Rifleman are in a really weird place as they are meant to be aggressive but as others have stated just one getting caught in supression can really mess you up.
funny how you compare them to IS and penals, since when do riflemen have to fight them? NEVER lol maybe next for a reason to buff grens ill compare them to Obers yeah?. Regarding riflemen, they mostly beat grens and volks in the early game. the only thing you need to be wary of is the mg42.
If you bothered reading what i said, they need smoke back on them. OKW struggles more vs suppression then USF who LITERALLY have a t0 mortar
