A plastic surgeon has called for a change to the way a German battalion does its rifle drill after its elite soldiers started developing breasts.

Dozens of soldiers in the Wachbataillon unit (Guard Battalion), which performs drill displays at official events, have complained about over-developed breasts on their left-hand side because of the way they clasp their rifles.

It is understood the repeated slapping of their rifles against their chests has stimulated hormones, causing a condition known as one-sided gynecomastia.
