The German Herald reports that men serving in the elite Wachbataillon unit of the German army are developing breasts on their left pectorals. A doctor who is treating the men says that their trademark close-order drill is at fault, as it has the men repeatedly, violently slamming their guns into the left side of their chest, stimulating mammary growth.
The condition - called one sided gynecomastia - has been diagnosed in 74 per cent of battalion members who presented to army medics with concerns over the growths.
Director of plastic surgery at the military hospital in Berlin, Professor Bjorn Krapohl, confirmed: "There is a very significant link between the activity in the Guard Battalion and the development of the breast on the left side.
"They need to change the way they drill. The constant slamming of the rifles against the left hand side of the chest is clearly a significant factor," he added.
