4Flying Sniper Bots
Of course, the people shooting at you are still humans, and humans can be killed. So that's still... sort of fair, right? Well, until they replace the snipers with robots. Who can fly. And shoot far, far more accurately than any human.
Unmanned drones are already all over the news, spotting terrorists in the mountains and even blowing them up sometimes. But researchers never stop looking for ways to make the concept more terrifying.
That's why they're building ARSS (yes, it's pronounced "arse") to straight up murder you from the sky while the pilot lounges comfortably on a recliner miles away drinking a cocktail out of a halved coconut.
ARSS is nothing less than a goddamn aerial sniper bot, complete with a .338 rifle that fires seven to 10 rounds a second, with "extreme precision." Though that two-word phrase seems a bit insufficient for something that can fire large caliber bullets that will punch through body armor from 10 football fields away. Silently. From the sky.
For the time being, aerial drones aren't being designed to be truly autonomous, at least until Skynet boots up. They have the ability to navigate pre-programmed flight paths, but for now, they require a human to control the finer flight control and to actually fire the weapons. Though the hyper-accuracy comes from the software, which sort of does auto-aiming. Hey, it's just like an FPS game! Finally, a job our generation is over-qualified for.

Apparently it's no longer okay to just flatten a whole city because there might be a few soldiers holed up there. So, you're a savvy terrorist group, and you've set your base up in a building nestled between an orphanage and a kitten factory.
Unfortunately for you, the Air Force has been testing what are called "Focused Lethality Munitions," or sniper bombs. They are being designed to drop out of bombers, fighter aircraft or even drones, use GPS to guide them to their target, and then kill everyone inside the building without so much as rattling the windows of nearby structures. No word on whether a pleasant female voice announces "you have arrived at your destination" before blowing everything to hell.
The sniper bomb's warhead consists of a "multiphase-blast explosive fill" made of DIME (Dense Inert Metal Explosive). The number of letters it takes just to name the blow-uppy parts is testament to how scary this thing is. Instead of a normal explosive wrapped in a crunchy shell of steel, it is held together by a carbon composite that murders everything in the room without harming the structure of the building.
DIME in action.
