The buffalo soldiers were expected to be the weaker lot - not as good as the white soldiers, most people who were in the army did not have much hope for them.They did not get as good quality guns,they had old uniform given out to them and got second priority after the white soldiers-I.e if there wasn't enough tents for both lots the white soldiers would come first so they would get the tents while the buffalo soldiers would have to sleep on the ground.Racial Abuse was experienced continuously, at the start of the buffalo soldiers time , slavery had just been abolished so it was difficult for black soldiers to be seen equal and free to the white soldiers who were used to treating them horribly, and saw the black soldiers as unable and useless.The black and white soldiers were also segregated into separate lots.
Now that is not the case, racism is not tolerated even though unfortunately it still happens in some cases.
