Except non-doctrinal USF has neither rocket artillery nor anything with anywhere close the combination of raw stopping power and durability of a Brummbar. The Scott acts like no other unit because it has to fit a very unique niche.
Axis team should've made rocket arty to deal with the heavy support weapons play that was preventing them from making a move against the Scotts instead of doubling down on tanks.
Speaking of the new visuals, I would suggest changing the UKF Assault Officer's bodyguards to the new Raid Section models. Given how the Raid Section now looks like British paratroopers, it would be a much better fit for the Officer than the regular tommies he currently hangs out with.
