An Army instructor is facing a court martial after filming a recruit who was reduced to tears as she underwent brutal training.

Mobile phone footage of the incident was uploaded to Facebook and has been viewed more than 300,000 times.

It shows a corporal subjecting the distraught trainee to a torrent of verbal abuse during a bayonet exercise.

After wading through a stream, the recruit was summoned before the instructor, who repeatedly yells that she is “f------- weak” and demands to know whether she is a killer or a mouse.

She is marched towards a pile of sandbags which represent the enemy and ordered to attack them but is chastised for her efforts.

The corporal then feigns sympathy and asks why she is crying before he launches another attack and says she is “nowhere near the end”.

It comes just weeks after the Army launched a new “softer” recruitment campaign targeting a broader base, which emphasises that it is okay for soldiers to cry.
