Now, a hands-free water pouch for the thirsty Australian soldier

Australian soldiers on active duty in hot environments may soon be able to have a drink of water without taking their hands off their weapons.

The Defence Science & Technology Organisation (DSTO) recently tested the comparative use of conventional water bottles against a 2.5 litre plastic pouch which sits inside a back pack and includes a straw-like tube that allows soldiers to drink on the move.

Soldiers were asked to test the two water delivery systems over four successive days during a gruelling daily 8 km patrol and mock assault on enemy positions.

DSTO scientists monitored their water intake, sweat and heart rate, body temperature, comfort levels and mood states during the trials in Queensland.

The soldiers unanimously preferred the hands-free water pouch over water bottles, stating that it was more convenient and operationally superior.

"Our soldiers must have quick and convenient access to water to counter the increased risk of heat stress and dehydration caused by operating in the heat and in the wet season humidity of northern Australia," said Chris Forbes-Ewan of DSTO’s Combatant Protection and Nutrition Branch.

"The tube attached to the water pouch means the soldier can drink whenever required without losing concentration or interrupting work to pull out a water bottle," Forbes-Ewan said. "Doing away with heavy water bottles hanging from the belt also means less fatigue and less strain on the back and hips," he added.

DSTO’s final report to the Army will recommend that consideration be given to replacing water bottles with a hands-free water delivery system for the soldier on the move.
