Unmanned Aerial Vehicles scanned the horizon for enemy action. Jackal vehicles with their awesome firepower raced ahead using the latest surveillance and targeting systems. Infantry stood ready to strike with deadly sniper rifles, mortars and grenade machine guns - this wasn't a major operation in Afghanistan but the UK's largest demonstration of military equipment purchased urgently for troops in Iraq and Afghanistan.>> Hundreds of pieces of equipment and over 500 people gathered on Salisbury Plain for a powerful demonstration of the advanced technology and cutting-edge equipment that is supporting our troops on operations.>> From the heavily armoured Mastiff patrol vehicle - a hero of recent operations in Afghanistan, to sophisticated thermal imaging sights and the latest state-of-the-art cameras and remote weapons systems - all were on site and demonstrating their effect to those present.>> Baroness Taylor, Minister for Defence Equipment and Support said:>> "The Urgent Operational Requirements (UOR) process is an undisputed success - over 3Bn of extra money has been spent on new equipment for operations in Iraq and Afghanistan - from new armoured vehicles like Mastiff and Ridgback to remote weapon systems which are protecting the soldiers in their bases.>> "Working with our partners in industry, we have responded quickly to the evolving and often unpredictable threats our soldiers face on operations. We have listened to the feedback from the ground and procured state-of-the-art kit to meet the urgent needs of our troops. The large display of equipment here today is testament to the effectiveness of that UOR process.
