Many settlers were willing to leave their homes and head west due to the dream of attaining a better life, usually thinking of the possibility of acquiring free or cheap land.

The correct option is the number 3
From the beginning of the war, and despite the policy of isolationism, the USA helped England with armaments, food and financial assistance. When the country entered the war all its industry changed as well as its society and lifestyle. Young men went to war and women took their places in working life. The industry transformed completely and went from producing consumer goods to producing armaments and military supplies to face the great war.
What war is this involving? If WW1,
Distinctive bright blue uniforms, though earlier in the war they carried dark blue uniforms with red trousers.
Here are why the other answers are incorrect:
A. No side really used camouflage on most soldiers. This was a practice that was started in (with the Germany) WW2, but eventually grew with the years to come. And for guerrilla warfare, the French didn’t use it. They used napoleonic tactics in the early stages of WW1.
C. I believe the most common style of close combat was the bayonet charge/usage, which was used by all sides.
D. Most sides were using older rifles, including the French, which were from the 1880s-early 1900s.
