The correct answer to this open question is the following.
What describes Native American involvement in the American Revolution was that Native American Indian Tribes wanted to protect their lands and that is why some have to take sides. Some native Indian tribes sided with the American colonist because one way or the other, they already have a relationship with them; good or bad, but they already knew them. Some other tribes sided with the British troops under the promise that they not only would respect their land but even give some land that had been occupied by colonists.
