Thanks for the suggestion. I'll compare the two units in detail and see what is the best way to make them different from eachother.

@SneakEye What about making Assault Guards become a kind of high-qualitiy basic infantry like U.S Rifleman?Which will be equipped with grenades and smoke grenades and SVT40,and can be upgaded with 6 ppsh

That penal battalion has 6 SVT and the Shocks have 6 ppsh, I don't think this will make the assault guards more usefull. I'm thinking about a sprint ability to make them more 'assault' guards.

My point is that Assault Guards will not be a kind of "Assault"Infantry,but can replace conscripts as a kind of basic Infantry,and can be choosed to be armed with DPs from HQ to increase mid-long ranged firepower or to be armed with normal PPSH to become cheaper assault infantry.However,,assault guards will have more abilities like oorah! and AT-grenades in order to do some things that conscripts do.In a word, the position of Assault Guards can be kind of similar to the penal battalion is the campaign

As for original weapons,we can use SVTs or introduce a weaker version (SVT before buffed),or make it use mosin-nagants that are armed by Guards Rifles
