The U.S. Air Force is developing tiny unmanned drones that will fly in swarms, hover like bees, crawl like spiders and even sneak up on unsuspecting targets and execute them with lethal precision.

The Air Vehicles Directorate, a research arm of the Air Force, has released a computer-animated video outlining the the future capabilities of Micro Air Vehicles (MAVs). The project promises to revolutionize war by down-sizing the combatants.

'MAVs will become a vital element in the ever-changing war-fighting environment and will help ensure success on the battlefield of the future,' the narrator intones.

'Unobtrusive, pervasive, lethal - Micro Air Vehicles, enhancing the capabilities of the future war fighter.'

Hovering: Micro Air Vehicles (MAVs) are the future of the unmanned drones program, according to a new video from the Air Force. The Air Force has already developed a drone capable of hovering like a moth

Perching: The video, released by the Air Vehicle Directorate, shows a pigeon-like drone that can draw power from an electrical wire while its camera watches a target

Crawling: The drones will be equipped with legs so that they can crawl through tight spaces like an insect

Killing: The video demonstrates how MAVs could be used to sneak up behind unsuspecting targets and kill them with a single, lethal shot

Lethal: The drones could be equipped with incapacitating chemicals, combustible payloads or even explosives 'for precision targeting capability'

Swarming: The drones couple be dropped en masse over a battlefield or a city and would work together to create a complex surveillance network

Working together: The drones would use advanced software to navigate by 'sight,' rather than GPS - which can be blocked by buildings or by jamming from the enemy
