Answer 1

Flying stuff is light and easy to punch holes in, you just need a lot of spread to hit it. Tanks however are easy to hit, but are heavily armored, usually with reactive armor that will detect projectiles and create outward explosions itself to pre-emptively detonate incoming missiles, but this armor is mostly on the side so anti-tank missiles typically lock on to the tank, then fly up and hit it from the top.
