Why did Native Americans give African American cavalry soldiers the name “Buffalo Soldiers”? (Select all that apply.)  (I know that 2 and 4 are correct. Are those the only two?)

1. They killed all of the buffalo on the Great Plains.
2. They were fierce fighters like the buffalo.
3. They fought herds of buffalo for sport.
4. They had dark, curly hair.
5. They wore buffalo-fur jackets in the winter.
