Since the introduction of the USF mortar riflemen simply need to be toned down.
If it was up to me, I would relocate up ALL t0 support weapon
2-3 squad together but what if they manage to get cover for each squad correctly does it still count as blober
because me my self also did confused why im treat other mainline inf way different from riflemen
They are very different because USF does not have any alternative infantry other than very few doctrines, but riflemen are very adaptable. Soviets have guards and shocks. Ost has Pgrens, and the rare Stormtroopers. OKW has Sturmpios, Jaegers, Obers, Falls, and even the Kubal. USF has Airborne which costs too much manpower and arrives a bit too late. Not usable inf such as Recon support IR pathfinders and paras. And finally Assault Engineers where they die too quickly to be any use.
I would like to remind all that double-bar riflemen are actually weaker than panzergrenadiers. The Vet 3 RA is tone down in the WBP so they are, in my opinion, are largely fine. USF has other larger problems that could be address.
