How to fly national flag?

Facing the display, from left to right: US flag, state flag , company flag. If you are flying them on two poles, place the US flag on the leftmost pole, and the state flag over the company flag on the right pole (check your state Flag Code to be sure this is acceptable).

The correct order of precedence is:

The US Army was established in June 14, 1775.

The US Marine Corps has had precedence over the Navy since 1921. The Marine Corps cites its origins to legislation of the Continental Congress establishing the Continental Marines on November 10, 1775.

The US Navy (until 1972) dated its establishment to legislation on March 27, 1794. Today, it dates its establishment to October 13, 1775, when George Washington, under Continental authority, took command of three privately-owned schooners to intercept British supply ships near Massachusetts.

The US Air Force became an independent service in 1947. It traces itself back to the Aeronautical Division, U.S. Signal Corps (part of the Army) in 1907.

The US Coast Guard dates itself to the founding of the Revenue Cutter Service on August 4, 1790, by Alexander Hamilton. The modern Coast Guard can be said to date to 1915, by act of Congress.
