Mines, Oorah to do the flanks the faction needs to do as Axis sits behind OP42s and LMGs, Mollies, Trip flares, flame throwers, DPs, .50 Kraut mower.
You need to get these things to keep your infantry in the game.
Also demo charges. There is never an excuse to float muni.
Think about this in comparison to the other factions. You HAVE to use smoke as USF, you need to upgrade all your basic infantry with weapons as USF, ect.
For OKW it's pretty self explanatory, you have high costing munition upgrades and reduced income.
Ostheer is probably the most MP intensive faction, you need Muni for medics, upgrade all your basic inf, expensive mines, ect.
Soviet's just don't have as much upgrades, most of the stuff you high lighted are abilities like the demo, molotovs, oorah, and mines.
