If anyone has seen recent US military commercials, they put a lot of emphasis on remote-control & unmanned vehicles. A pessimistic view would be that they want to present a safer working environment for its military, which is currently heavily deployed overseas and might have trouble recruiting. But I think that is the way of the future.
It takes a decade to train a good fighter pilot, but he'd quit after serving x number of years, or get sick, etc. It takes much less effort to train a UAV operator, and attack UAV/missiles in sealed TLC (transport-launch containers) never gets sick, take vacations, or retire early.
