Those must be HEAT rounds. An AP round would not have the velocity to do anything, anti-personnel would not penetrate tanks armor but would kill crew if dismounted or a hatch is left open

The typical setup I’ve seen for FPV drones is RPG warheads or small mortar shells for drops. I’d love to see one drop 152/155mm shells though.

Those aren't artillery shells though, the explosive part of those weighs seven kilos, which is too much for the mass produced drones they use. As others mentioned, they use RPGs (3 kgs), mortar shells (~1.5 kgs), grenades (<1 kg), sometimes land mines, and specialized drone explosives for suicide drones.

I do like seeing the production facilities of these drones, how they simplified the designs but also made design decisions to deal with the scale, they're built so they can be stacked easily. Mind you, this is probably the case with these drone show drones too.
