No, there's no particle cannon, aurora bombers, or laser tanks.
F-22A Raptors exist, Tomahawks are completely different from the ingame versions, and the microwave weapons in testing have no tank version, nor do they burn people alive in a big field around the vehicle. XD .
What's really funny is the one thing you say you're waiting for them to invent, the combat robots, are what's actually already in service, in the form of the Talon drones (Which are likely the inspiration for the sentry drones.) , and a plethora of UAVs, the most famous of which is the Predator.
