British soldiers from the Grenadier Guard shared a video on Twitter showing the excruciating consequences to not having adequate battlefield awareness during training.
In the video, a gaggle of soldiers equipped with SA80 rifles are seen carrying a troop on a litter during a simulated mock casualty evacuation, when one of the soldiers inadvertently walks into a sharp broken branch protruding from the ground.
A groan can be heard as onlookers, including the soldiers providing security, look toward the soldier, who falls backward.
"Maintaining your 360-degree battlefield awareness is essential in the jungle," the Guard said in the tweet. "You never know what it has in store for you next."
The Grenadier Guards' roots dates to 1656, and it's one of the oldest regiments in the British army.
Soldiers from the Guard have participated in all of the country's major wars, including current fighting in Afghanistan. In addition to conventional war-fighting capabilities, the Guard says it uses unconventional equipment, such as quad bikes, to mobilize quickly.
