Answer:
for more troops to fight in the war so not as many mainland men had to be used.
Explanation:
Some colonial troops remained in Europe and were used for manual labor. They dug trenches, moved supplies, and cleared battlefields.
Machine Gun. Machine guns needed 4-6 men to work them and had to be on a flat surface. They had the fire-power of 100 guns. Large field guns had a long range and could deliver devastating blows to the enemy but needed up to 12 men to work them. Submachine Guns. The Germans first introduced the MP18 Bergmann Muskete submachine gun – called a "machine pistol" – in 1918, in the closing months of World War I. The light-weight weapon had a rapid rate of fire and was easy to use in trenches and other confined spaces.
There were many events that helped develop the ambience for World War II, but the inmediate cause was the German invasion of Poland in Hitler's attempt to expand his territory and influence to the rest of Europe after terribly losing most of what made Germany a major world power in WWI, which led to Britain and France taking charge to stop said advance.
