That enemy drone, acting as a spotter, could cost the lives of many UA defenders by giving away their positions or correcting artillery fire. Our UA Mavic probably had the grenade and would have had to drop it anyway to try an take down the enemy Mavic by ramming it. So...might as well try and drop the grenade on the enemy Mavic first!

I imagine it's routine to drop things that explode before ramming the drone from above.

So I am guessing a lot.

Though it started with lion king.
