Soldiers have been taking part in a Call Of Duty-style experiment in Wiltshire to help work out what new technology will best help the Army deal with future threats.
The "virtual military simulation experiment" uses software ideas from the gaming industry to put soldiers through their paces.
The £1 million experiment, at the Land Warfare Centre in Warminster, allows soldiers to test possible technical advances the Army does not yet physically have, and to train in a range of environments, from urban to rural, inland or coastal.
Set in a 3D virtual battlefield, it has some similarities to the popular computer game series Call Of Duty.
– Major Mark Davis, Officer Commanding C Company, 2 Royal Welsh
"There are differences obviously. Call Of Duty is a game, so it's quite fun, whereas this is an experiment so it doesn't have the same effects."
