The German Army was equipped with the new IFEX Hand-Water-Pistol. The pistol uses a new impuls technologie, that works like this :- (only) one liter water is pressed into the water tank with six bar- the pressure chamber is filled with air up to 25 bar- the shot is fired by a high-velocity valve that opens for 20/1000 of a second- this impuls shot hits the target with 400km/h or about 250 miles/hAdvantage in case of fire : the normal cooling space for one liter water gets decupled; from normally 6 square meters up to 65 square meters - with one single shot.
