There’s an excellent YouTube video that I can’t find because it keeps thinking I want tank top t-shirts.

Anyway anti-tank rounds have two levels to them the first is a charge that explodes to weaken the armor and the second one goes through that to penetrate.

If the first part explodes prematurely in theory it will have a lot less penetrating force.

That's an Oshkosh M-ATV, and if it has camo netting on top, it's a much lighter/simpler structure than the big cage on the pictured tank. There are some versions of the Oshkosh with light armor on top, but just regular old armor plate...probably for overhead snipers.
