Over a million MP40s were produced for German forces during the Second World War, and they were seen as an excellent second-generation weapon - perfect for new tactics.... They were originally supplied to Nazi paratroopers for parachute invasions; however, after devastating losses against the submachine gun-equipped Soviet armies, it was agreed that they could have a greater effect with assault forces. Movies and games often choose to give these weapons to the typical German soldiers, although in reality they were less prevalent on the ground, in comparison to the Karabiner 98k rifle. The German army struggled to finance production of these two main guns during the war, due to the costs of mass production for such an expansive army. The MP40 used the 9mm cartridge to devastating effect.

The First World War caused devastation across Europe, and over 70 million soldiers were involved in the fighting. It's near-impossible to summarise such an event, and there was no single cause of this war.

Unsatisfactory peace settlements from World War I were probably the greatest influence on the start of the Second World War. The Wall Street Crash was also a major factor, as it caused severe unemployment in Germany. In 1939, Hitler invaded Poland, expecting Britain and France to let him get away with it as they had before. However, they admirably refused, and by September 3rd the two allies honoured their agreement with Poland by declaring war on Germany. What followed was the deadliest conflict ever, which involved soldiers from around the world.

Despite getting incredibly close to overpowering the Allies on numerous occasions, they resisted with help from the USA, and the war ended in 1945. Hundreds of different weapons were used in both wars, but you can see a small selection below:
