IMO, "speshul" commander should get next layout:
1 CP: tankhunters section with more utility abilities - like tank detection, cloak in heavy cover, maybe special smoke grenade, like german blender, but works only for veichles. Maybe light AT-mines, like americans have.
3 CP: ressuply halftrack with Royal Recovery team in it + rework of ressuply HT itself - maybe one-use OKW-style medcrate for 10 mu, brens, piats AND Vikkers after research.
7 CP: incendiary mortar barrage
8 CP: heavy arty
10 CP or 12 CP: crock itself.
I am no expert in game AND in brits (just picked them in november during sale) but I think this will at the same time keep it separated from the rest with their distinctive squads and ability and will make it somewhat useful in 1v1 as well.
BTW, do anyone have any clues how "Hold the Line" works? It seems too random for me - sometimes it lights up my whole frontline and sends out 4 typhoons, and sometimes literally nothing happens, sendnig my 200 muni down the drain.
AT section already have tank detection a passive ability would be fine
Recovery team in a halftrack would be waste of popcap
No need for med kit since they can heal themselves
Remove heavy arty and add anti tank strafe plane or replace flame mortar with anti infantry strafe plane
