An army is supposed to have flexibility to switch from tasks without losing its efficiency. If the British Army was used to provide for security for the Games, then it should not, in any way, make them training wise or operationally unfit. It is correct that the training schedules and leave planning would be skewed, but then it can be made up with some imagination. Training schedule could be truncated by cutting down on the routine and repetitive which are there more of a refresher and shortfall in leave recompensed with money. Since operational tasks in Afghanistan has not been affected, there should be no worry about not being able to meet operational needs. Therefore, what could be the grounds wherein it is felt that the British Army will take two years to return to normal?
