WATCH: U.S Marine Soldiers Made an Unmanned Aircraft System & STALKER Marines conduct flight operations

Very complicated as is all military equipment and requires lots of training and expertise.

Keep that in mind when someone says the USA does not have troops in Ukraine,,, all of the equipment and weapons we sent them requires the same amount of instruction to operate and maintain.

better watch out for those greys sabotaging equipment with their interdimensonal space craft

for future reference OP....calling a Marine a Soldier in person might not work out well on your behalf.
