those aren't squads for the most part
Sniper vet 2 is probably the only thing there you want spotting for your ATG like you can with pio/path/jaeger.
Rest of those are emplacements (lol), vet abilities for emplacements (lol) or vehicles. AEC and valentine aren't bad but they're not T-70 tier that unlocks vet3 in a heartbeat.
I was simply pointing out the sight option for UKF and they have some.
Personally I would test making the pyro upgrade a side grade instead of straight upgrade.
Change could include giving the squad scope enflied, removing cover mechanism and reducing DPS making the unit a scout that that hit light and is used more for utility than fighting (as most reckon squads should be). If need a temporary ability could be added (maybe kills with critical under a threshold similar to other scoped weapons)
