Final answer:
The Army flag was dedicated on June 14, 1956, which is separate from other historical events involving the U.S. Army or other military branches.
Step-by-step explanation:
The Army flag was dedicated on June 14, 1956. However, this question may be inquiring about a specific event involving the U.S. Army, which is not provided in the references. If the question refers to the iconic image of U.S. Marines raising the flag on Iwo Jima, that happened on February 23, 1945. Still, that occasion did not involve the dedication of the Army flag. It is important to note that the creation of the Department of Defense in 1949 reorganized the different military departments, which included the Department of the Army. Nonetheless, the direct answer to the question about the Army flag dedication is June 14, 1956.
