The British Army is short on blank ammunition used for military training exercises. As a result, soldiers playing war games may have to shout "bang, bang" when they fire. From the UK Telegraph:
A senior Army officer said that the ammunition crisis was "shambolic" and came at the worst possible time for the Army.Link (Thanks, W. Vann Hall!)
He said: "There is nothing more dispiriting than soldiers having to go on exercise and shout 'bang, bang' because there is not enough blank ammunition. Any benefit from the exercise will be lost because soldiers just won't take it seriously. Why should soldiers who are being sent to Iraq, where their lives will be endangered, be forced to shout 'bang' in training because someone in the Ministry of Defence can't do basic arithmetic? It's a disgrace."
