Army strong

The Army is the largest, oldest, and most senior branch of the U.S. military, and can be traced back to the Continental Army, and was founded in order to fight in the Revolutionary War. The U.S. Army is comprised of the Regular Army, Army National Guard, and Army Reserve, and makes up the land warfare branch of the U.S. military. While General is the highest rank one can achieve within the Army, the U.S. president is the Commander-in-Chief and head of the military overall.

This we’ll defend

America is known the world over for being a strong military power, and Americans tend to have a lot of confidence in the military. The United States might not have the largest military in the world, but it outpaces all other countries in defense spending.
