Interesting suggestions.
Greyhound in LT tier wouldn't work - it would be too powerful. It would hit the field at the same time as Luchs while countering it effectively. I'd prefer to reduce the MP cost of the m20 so that it hits the field earlier, and has more of an effective window. Something like 260mp would be a lot more manageable.
Swapping AAHT and AT Gun would make sense though. That would give the Captain a Light Vehicle specialty and LT the support weapon specialty.
Fair point on the Greyhound being to powerful
Swapping the AT gun the most important one yeah.
But more than anything the dismounted bazooka team is so risky, would be nice if it got a toggle ability where the M20 gunner pulled up a zook and fired it from the hatch instead of the .50cal, would be great for chasing down 222s. But with the 57mm at Lt could be too much, so if the zook is removed completely it could be used to justify the price reduction you suggested? Or maybe make the shooting the zook from the hatch a munitions ability. So it could be used as an occasional chase-down after using the At Gun.
tbh more than anything I'd love light vehicles to retain some kind of use late game as support/utility vehicles. e.g (M20)

I feel like the T70's recon mode makes it useful in spotting for Td's and at guns late game. and it's always decent at chewing through infantry like the luchs.
I don't know what could be given to the 222 tho? Perhaps give it an upgrade or vet to a command vehicle and replace the P4 command tank with something else in the commanders.
And i'd make the brit treadbreaker shot on the AEC work in one shot, it could make up for the snarelessness of brit infantry. Have one single very powerful, long range snare in exchange for none on inf. AEC could then be good for snaring heavies late game.
And Making the teching linear would be amazing, perhaps give LT the 'on me' ability on top of the smokes so there's just one officer squad for rifleman to follow, then just remove CAPT and make that tier have no free unit.
So after all of that ^
T0 - Inf
T1(free lt squad) - Rifle support units (.50cal, 57mm, M20)
T2 (no free unit)- Light vehicles/ heavy fire support (howie/Stuart/AAHT)
T3 (M20 car upgrade for forward retreat) - Tanks
