need something that would make them work without guards (or guards in tech). Penals are good candidates, even if that would mean these units somewhat overlap.

These standart double 222 with option to get 3-4, or okw LV rushes. Is uncounterable without guards. Even zis+mines isnt enough.
And LMG grens are superior to penals even on mid range so with penals you're not gonna able to get them out of green cover/garrisons. And going AT partisans just for 1 222, will destroy your late game unless you tech with all that fuel...
+1
but partisans choice looks best since playing with t3476-shit in late is better than playing with 1 ATG vs 3 222/251.
counter snipe since you have advantage due to much better sniper cloak. Use your extra squad to your advantage. Guards arent counter to 222. Take both fuels with extra squad and 222/251 and he will never have anything but few infantry.
you can clearly see how op and cheap t70 is in this game. T70 (first vehicle) arrived just AFTER P4 and long after 2 axis lights. T70 survived some time even.
