Suggestions:
ukfBRIT. Replace M3 HTAA by AVRE. Axis has heavy tanks in the NewCom. How are you going to counterpart? therefore it is better a AVRE that allows the strategies in the matches
usfUSF. Replace Dozer Blades by Dodge WC51. Making barriers to cover is not very useful. is better a Dodge, which would introduce many initial strategies.
sovietsSOV. Replace Airborne Rally Point by Designate Command Vehicle. Axis has heavy tanks in the NewCom. How are you going to counterpart? therefore it is better a Command Vehicle that allows the strategies in the matches
I really like the idea of AVRE in this commander it fits with that "urban" assault theme but it will be a bit OP with Thompson Tommy (complete shut down of Axis infantry).
USF - I say no - this doctrine is lacking that "punch" and jeep is mainly a "hit & run" tactic.
Soviet - LOVE the idea but will this fit the theme?
