Ever considered/discussed for a different approach, like increasing armor ?
Unless it has 200+ you only have protection from the Panzer IV and Puma, units the M10 already clubs and doesn't need to club harder.
We're still discussing stuff for the M10 which is a difficult unit to get right. Even if the M36 Jackson got nerfed -not here in Commander Revamp- it's still the situation of 'AEF needs a very good AT vehicles stock' so Jacksons will always be that long-term/end game option. And moving M10 to the core, it's still the issue of USF only having 2.5/3 tiers of tech. It earlier comes too early from two officers or slightly too late/better options are around.
We've discussed some issues from ideas/changes though in the background:
-Self-Sight means M10s can easily hunt and snipe most things out of range.
-Cheaper cost means you're getting almost two of these for every armoured vehicle the enemy gets that isn't a StuG G or Ostwind.
-We had an idea about cloak, but given how cloaking works with phase tech, likely a no-go.
