Considering it has a tanky Sherman with WP shells to shutdown pak guns, Rangers, very strong anti-garrison tools, Sprint Smoke, and Calliope, what do you want it to do? Yes, it doesn't have strong anti-tank, but the USF already has Jacksons supported by 57mm ATGs and zooks.
It's got 2 gimmicky abilities, an unreliable and underperforming rocket tank, an arguably good sort of gimmick for the Sherman and Rangers, who are probably going to be the best thing about this commander by far.
Besides it being too situational for anything, what's this going to provide in comparison or over some of the other commanders like Armor or Mech Companies? Both have call in infantry and better vehicles to deploy as well, not to mention that Mech Company even has the Dozer upgrade as well, what is this good for anyhow apart from the handful of maps that feature an urban environment? If I want to go Rangers I'll just play with Heavy Cav, I can get smoke and a Pershing as well as my riflemen being able to build defenses.
I even told Sander that this commander is probably the most unpopular of the bunch and he agreed with me on my Jumbo thread so I don't see what you're trying to defend here apart from bad decisions on the design part of it like so many commanders in need of a revamp before this.
I'm just pissed off since Tac Support and Rifle Companies need the revamp badly and there was time and potential for a better commander overall here that won't need one but sadly it is what it is.
