Got a war to fight? Want to fight the enemy and not get complaints about the lousy food or inadequate air and ground support? Then, send in the ROV’s with drones that could spread out, each with its own propulsion and surveillance equipment that can cover a larger area, sending information to the mother ROV, and then back to the command center for interpretation. You can even arm them with active systems to take out all threats that are designated by their human controllers automatically(choose from the arsenal of pistols, sub-machineguns, sniper rifles, grenade launchers, rocket launchers and all the stuff you could think of they’ve tested it).
The US military has a lot of autonomous vehicles that can be armed with handguns, rifles and even rocket launchers for doing jobs which could be too risky to send in people. These robots will be cheaper and they can operate indefinitely or as long as their batteries last which they can re-charge through solar panels as they switch to low activity modes, shifting to reconnaissance mode in long-period missions as they charge up. Once they get powered up to continue their mission, they get back up and go rolling away to complete the mission. Patrolling borders may be easier this way, with autonomous robots that do not get hungry or are designed not to bee too affected by the temperature extremes. Clearing mines in hostile waters is easier and faster without the risk to human life.The future of “Terminator” may not be too far fetched as it seems, for there is no boundaries to the technological wonders we are seeing now (not to count the ones that are for military use only, for the ones you might be seeing are already old-tech and they are sure to have better more improved versions way in the deep recesses of those converted missile silos deep underground which have been converted into top-secret development laboratories) and will be seeing in the near future.
