As a realistic and logical person, I feel obliged (just as you were to post anime shtuph in the first place) to point out that two squads of Marines, a Stryker MGS (Mobile Gun System with a 105mm cannon), and two Stryker ICVs (Infantry Carrier Vehicle, armed with a M2 Brownings and 40mm grenade launcher) would be able to eliminate that entire group of a couple/several dozen people, what appears to be a large-caliber light tank, and what appears to be an AFV armed with an autocannon or large-caliber gun. I'd say 130mm on that tank, and a 40mm gun on that AFV, disregarding the item above it.

There's also the fact that none of those look to be in a prime fighting condition, experienced, and without armor, proper clothing, or tactical gear to speak of.
