I am puzzled by whatever the ground drones were supposedly firing. They looked like shell & cartridge but there was no barrel, without which they're not going to propel the shell anywhere useful. But they jetted off like rockets and those need a bit of tube guidance to help them launch.
So this implies some kind of internal flight guidance, to home in on enemy targets. This is why aircraft ordnance costs a five-figure sum, minimum, per round. Profligate useage, as depicted should empty the coffers faster than the tank division could.
Off topic but I recently watched episode 2 of Greece with Simon Reeve, in which he reckoned Greece was induced (euphemism) into buying German-built tanks and this contributed towards its later debt crisis in a big way. And now Germ… I mean the EU lays down the law with its austerity plan for Greece. There's nice, for
you.
Clarification: any and all inducements will have been by private business people, not the EU, as such.
