Methods of warfare including gas, tanks and heavy artillery

Methods of warfare including gas, tanks and heavy artillery.

1. Tanks were introduced by the British during WW1 - hoping that they would be able to crush barbed wire and protect troops from machine gun fire. Tanks were heavily used during Blitzkrieg tactics, most notably by the Nazis, and helped Blitzkrieg become a completely unexpected and new form of warfare. They were the most significant weapon during the time and affected land warfare greatly, providing protection and confidence for troops and being able to travel through almost anything
2. Gas was used a lot during WW1; mostly mustard gas, chlorine, and phosgene. Mustard gas was the most effective, and after Germany had attempted with other gasses they realised that mustard gas was the hardest to detect, and so had the best effect on opponents. Burns from mustard gas were so bad that the result would mean that the soldier likely wouldn't be able to fight again - most of the mustard gas victims died after the attack from secondary infections. Gas was mainly used for physical harm as well as psychological effects, with soldiers always living in fear of a gas attack - only around 3,000 Brits actually died from gas attacks. 
3. Heavy artillery was very important in trench warfare, with infantry attacks rarely being successful if out of range of its artillery. Artillery was used to bombard the enemy infantry in the trenches - mainly firing high explosives, fragmentation, and sometimes gas shells. Heavy artillery was used to fight Blitzkrieg tactics against the Germans in WW2 - heavy guns were used to protect important harbours and coastal areas, usually unable to cope against modern warships and aircraft; the field gun was used by major armies, firing short but heavy shells.
