While i like this idea, at this point it seems like why not just replace the abilities with a Assault Engineer squad?
Come to think of it i think that USF commanders could really benefit from some kind of call in unit reshuffle.
Something like.
Rifle company: swap flamethrower for Rangers and the EZ8 for the 105 Sherman (for supporting the infantry) the rifle flare ability gets combined with the RE rifle grenade. (The RE flamethrower gets ditched because it has bad synergy)
Armor company: swap the 105 Sherman for the EZ8 because its a good all round medium armor (lets say it gets some stat tweaks if these changes are made)
Urban assault: Swap out the Ranger for Assault Engineers (to clear out houses). The rifle flare ability gets combined with the RE rifle grenade (the petrol bomb gets ditched because the assault engineers are all ready present to clear houses).
So in the end it would look like.
Rifle Company
Rifleman Field Defenses 0CP
Advanced Infantry Equipment 0cp (Rifleman flares and Rear Echelon rifle grenades)
Rangers 3CP
105MM Bulldozer Sherman
White phosphorus Smoke Barrage
Armor company
Assault Engineers 0CP
Elite Vehicle Crew Upgrade 0CP
M10 Wolverine Tank Destroyer 0CP
M4A3E8 Sherman ''Easy 8'' 0CP
240MM Howitzer Barrage 12CP
Urban Assault Company
Advanced Infantry Equipment 0cp (Rifleman flares and Rear Echelon rifle grenades)
Assault Engineers 0CP
M4A3 Sherman Assault Package 0CP
Cover to Cover 4CP
M4 Sherman Calliope 10CP
