Part of the photography I did with the HALO Trust was to document the task of battlefield clean-up. The ravages of war and conflict, in addition to human casualties can leave a devastating mess with consequences, particularly for the environment. Rockets, weapons, tanks, vehicles and aircraft are all part of it. And, of course, mines - both anti-tank and anti-personnel. A variety of kit and equipment is needed to do this, such as diggers, screeners and cutting machines.
