Machine guns Mowed down waves of soldier Artillery shells killed/hurt even more soldiers than the gun itself Aircraft Expensive but made little impact for one side or another because usually planes only fought each other leaving stalemate Poison Gas Blinded and choked victims, causing skin damage. Unpredictable weapon, wind can blow back the gas, hurting the throwers. Gas was fatal. Submarine Sank vital war supplies that were going from the allied side to the British Trench Warfare No mans land exceptionally hard to cross due to machine guns. Great defense but poor offence. Neither side gained land.

5. WWI Strategy and Technology  Stalemate???? Machine guns Rapid fire long range weapons The shrapnel, or debris, killed more than the guns themselves Aircraft Used to observe enemy troop movements Dropped gas filled balloons Poison Gas Choked or blinded its victims with agonizing burns and blisters Could be fatal It was one of the most dreaded hazards, it was countered with gas masks Submarine German U-boats did tremendous damage to the allied side, sinking merchant ships carrying vital supplies to Britain Trench Warfare Soldiers stayed in trenches and would attack the other side; however, the enemy would counterattack -> back and forth -> many deaths, but no side had the advantage -> stalemate
