How was life for an Army man in the late 1800's and early 1900's?

I am trying to find out how life was for the average army man in the late 1800's and early 1900's? please i really need to know.

I wish I could help--my GGG grandfather fought in the civil war and I have his records. But they are a little scanty, so I can't give any real interesting information. He was in the 23th Iowa Infantry and marched all the way to Louisiana, was promoted to corporal, wounded in battle and taken POW by the confederate army. He was released after the war ended an marched himself all the way back to Iowa. All that I know from this is that he earned about $12 a month for his service.
During the War, more men on both sides died from disease than from battle wounds. Northern privates received $13.00 per month if they had the good fortune to be white, $11.00 per month if they were black. The War department corrected this by the end of the war. They ate hardtack, sometimes crawling with weevils (no extra charge for the fresh meat), bacon, salt pork, boiled beef, called bully beef in the Navy and Salt hoss in the army, and lots and lots of coffee.
