Why were the native americans important to the french and indian war?

Native Americans were extremely important as allies in the French and Indian War, for a number of reasons:

1) The Native American demographic population allowed for a large scale recruitment of allies to their cause (whether French or British), usually bolstering the army's strength.

2) The Native Americans understood their respective areas of terrain, and can act as guides in planning, strategizing, movement, and direction during the war.

3) Trade and alliances were important in being able to sustain troops and organizations within the Americas. Hostile Native tribes that live in the region and continuously raid can prove detrimental to morale of the troops, and can punch holes into defenses as well as supply lines.

4) General good trades, in which Europeans can trade for needed material (such as food, wood, etc.) that would be hard or time-consuming to acquire on their own.
