So wake up and wish the United States Army happy birthday!
Since its official establishment, June 14, 1775 — more than a year before the Declaration of Independence — the U.S. Army has played a vital role in the growth and development of the American nation. Drawing on both long-standing militia traditions and recently introduced professional standards, it won the new republic's independence in an arduous eight-year struggle against Great Britain. At times, the Army provided the lone symbol of nationhood around which patriots rallied.
Cake would be appropriate today, I think.
UPDATE: More from the Army.
UPDATE: Also, it is Flag Day. With bonus details on how lack of precision in statutory language can give the executive great discretion in obeying the law.
But back to the Army.
