Doesn't this seem a bit redundant? Brits already have a commander with a halftrack call-in that also drops infantry weapon pickups (this one doesn't), plus Brits don't really have trouble in the forward outpost/reinforcement department.
M3 Stuart call in maybe?
There was a cool suggestion in the stream: replace the M3 halftrack with the M5 halftrack.
That means you're not using the same model as the Resupply HT, and brings the M5 Quad into the balancing scope.
Secondly, I think Smoke Raid Operation is a little redundant in the new UKF commander. UKF has a lot of smoke to begin with, and the commander also gives you 81mm Smoke and Assault Section White Phosphorous grenades.
Maybe replace it with Vehicle Crew Repairs? The M10 and USF halftracks are balanced around having decrew repair after all.
