The early Ukraine war FPV drones were armed with warheads from lightweight anti-tank weapons, like the RPG-7:

The newer drones may have dedicated warhead designs now, but the concept is similar. They carry high explosive warheads that aren't sold to civilians. It's the same reason the militias don't already have anti-tank weapons.

You can watch on YouTube people playing with 30mm diameter shaped charges (piercing thick metal plates). The anti-tank warhead is the same shaped charge of 90-130mm diameter.
