If you put the Thompsons behind racks and the satchel behind Vet 1, you could probably safely make them CP0.
That's an interesting idea. I like it but I think dodge + cav rifles as first two units would be rather OP since you'd basically be able to chase down and guaranteed wipe a unit immediately even with just the grease guns since they still have pretty respectable DPS at point blank.
I disagreed with #1 mostly because the thing comes unarmed and costs only marginally less than the kubel, which has its own weapon by default and the fastest repairing unit in the game backing it up, and the UC, which has crew repair for muni and a weapon by default. Dodge is also doctrinal.
Honestly, I think the best solution for the dodge is to make it unable to carry infantry but give it the .50 by default and increase cost to like 280 (because it has solid DPS). That way it goes from a cheesy wipe machine to a legitimate harassment unit and scout more like the jeep from Coh1.
I honestly don't have any opinion on #3. I don't really use the bulldozer upgrade that much, mostly because I actually like 76 shermans (I know that's an unpopular opinion lol).
