Its a 4 man squad with expensive reinforce and a 120 muni upgrade, it should be very effective against paper vehicles.
Infantry wreck them, smoke blocks los
Yeah, the only USF light that really gets anywhere near close to invalidated is M20s which are still pretty useful when dodging the 340 MP 120 muni squads that the enemy can't have a ton of quickly, and it's not only light that gets to be a waste of time in combat when good AT rolls anyway (the mines it has give it one of the best chance out of light vehicles to not become useless, too).
And WC-51s but most of us have forgotten their existence anyway so most won't mind.
