Will the US use unmanned ground vehicles or other robots intended to move over land and fulfill combat roles on Iranian soil?

US = US army or other armed forces/branches of government.

Robots = Vehicles or machines intended to move over distances over 100m without a driver physically touching any part of the vehicle (cord-operated do not count).

Combat role = Directly trying to cause damage or in direct contact/support of soldiers that do. Examples: medevac counts, moving containers in a logistical center does not.
