The British Army has this week launched the biggest military robot exercise in its history.

British troops on Monday began testing out more than 70 examples of futuristic technology including enhanced surveillance drones and unmanned vehicles.

The "game-changing" Autonomous Warrior experiment, which took place on the fields of Salisbury Plain, will last four weeks and test a range of prototype unmanned aerial and autonomous ground vehicles.

The exercise will end with a battlegroup experiment, where the best ideas and products will be tested in the toughest of simulated operational environments.

Williamson said the equipment could "revolutionise our Armed Forces".

"Our troops now have the chance to test out a huge range of robotic kit in what will be the biggest exercise of its kind in our history," he added.

"We're always working with the brightest minds in Britain and across the world to see how they can support our military of the future, but now the frontrunners have the chance to prove what they can really do on a battlefield."

One of the key areas the exercise will test is the autonomous last mile resupply. The 'last mile', which represents the extremely dangerous final approach to the combat zone, is crucial to ensuring soldiers have the food, fuel and ammunition to keep them alive.

The Royal Tank Regiment Battle Group from 1 Armoured Infantry Brigade are providing the bulk of exercising troops and taking responsibility of command and control.

Overall there will be over 200 multi-national, cross-service personnel. The US Army, Royal Marines, RAF and the Defence Science and Technology Laboratory (Dstl) will join industry partners and academia in working alongside them, experimenting with over 70 products and systems.
