Protective military clothing is frequently relied upon to minimise the risk of bodily injury for soldiers, especially those serving on the front line.
The US military is seeking to improve this protection and is introducing women's and men's underwear
that features armoured padding and will be standard in combat roles.
They look and feel like cycling shorts and have earned the nickname of 'kevlar boxes', in reference to their fabric.
The underwear has been developed to prevent dirt and debris from piercing the skin, and it is hoped that they will help reduce front line injuries.
Lieutenant Colonel Frank Lozano explained the undergarment's purpose to KVUE.
He said: "These injuries can be very traumatic to a soldier's life, especially a young soldier, who may have injuries to the groin region, who may lose reproductive organs. [He] may lose all of his legs, both of his legs at the hip joint."
