By sinking them!
No there were no tanks planes OR submarines in ww1. My friend Dennis ate them all.
Submarines typically use air tanks. Oxygen is very dangerous and very flammable. It's use is very limited on submarines for that reason.
They advanced inland to Caen and were held up by stiff resistance from the tanks of German 21st Panzer Div. ( the Allies were unaware these tanks were in Normandy)
General Patton used tanks effectively against the German tanks, but overall, German tanks were better armoured, and had better guns than any thing the allies had late in the war. Sheer numbers were the deciding factor. The allies were able to produce ten times the tanks the Germans produced.
In both battles, the German Army had over 45,000 casualties and lost 500+ tanks. The Allies had 27,000 casualties and lost 300+ tanks.
Submarines change their depth by use of ballast tanks. To dive, they open their tanks so that they become filled with water. They also angle their dive planes. To surface, they pump the water out of their tanks and fill them with pressurised air.
Submarines have ballast tanks in them.........when it has to go deep down, the ballast tanks are filled with water, which increases its average density in regard to water(Relative Density).....and when it has to come up to the surface it empties the ballast tanks...and it rises. That's it.
German submarines targeted Allied shipping. Any merchant ship that carried fuel, stores, weapons and ammunition or any other goods that supported Allied military activity were targets. If you could take away fuel for tanks, you could idle those tanks. Take away aircraft fuel and planes sit on the ground. Deny an adversary ammunition and you will not be fired upon, but you've gotten the picture by now.
The Germans had approximately 700 tanks, within reach of the D Day beaches. However, most of these tanks were under Hitler's direct control and he refused to release them until mid-afternoon on the 6th. By this time the Allies had landed over 300 tanks and many vehicles and the arriving German tanks did not engage until the next day.
Yes Germany did use tanks during world war 1, they use tanks alone with airplanes, gas masks, and submarines
they are used in submarines and tanks. some are used like a telescope.
