I not sure these UAV's were made in 1960's and 1970's

You could have land drones i.e. remote control cars or bomb disposal robots.

Bringing this thread back to life and reorienting it slightly, does anyone have house rules for drones? The only GDW rules I can think of for them are from the Twilight Nightmares scenario "Warlord," with its GCUX series of ground UCVs functioning like vehicles with a fixed initiative of 3. They're either disabled on a radio hit (for the smaller drone) or have initiative get worse if the radio is destroyed and have crew hits disable the on-board computer (for the larger drones). They seem workable, but I'm curious what others may have come up with.
