1 of 10: On This Day In Dragon History #OTDIDH, May 9, 1968: The @USArmy announces that in four months, the @101stAASLTDIV, up until then an airborne division, will convert into an airmobile division.

2 of 10: The "Screaming Eagles" would become the @USArmy's 2nd airmobile division, following behind @1stCavalryDiv. The transition allowed the division to conduct helicopter operations for increased tactical mobility in Vietnam.

3 of 10: So, what's the (very brief) backstory? Why did this transformation come about? We're so glad you asked.

4 of 10: In 1954, General Jim Gavin, famous #WWII commander of the @82ndABNDiv and strategic thinker, began pushing for an airmobile organization within the Army. At the time, the "Jumping General" was the Army Operations Officer.

5 of 10: A study of the Korean War revealed to Gavin that many @EighthArmyKorea units were not resourced sufficiently for reconnaissance. Gavin felt that the helicopter could solve this problem.

6 of 10: In 1954 Jim published a visionary article titled "Cavalry, and I Don't Mean Horses," in Harper's Magazine. The article was a breakthrough and speaks to the importance of the development and publication of innovative ideas and military concepts.

7 of 10: Over the next 8 years, the Army continued to develop this idea with many leaders such as Hamilton Howze pushing for its implementation. Interservice rivalry and a lack of strategic thinking at the @DeptofDefense prevented implementation until 1962.

8 of 10: In 1962, the 11th Air Assault Division was formed as a test unit for the concept. Three years later, 1st Cav was selected for airmobile conversion to fight in Vietnam.

In 1965, the 1st Cavalry Division (up until then in Korea), brought its colors to @FortBenning.

9 of 10: These two legendary divisions effectively swapped places: the @2INFDIV, then at Fort Benning, went to Korea, where it has been ever since.

10 of 10: The 101st was the next unit to reconfigure.

And now, you know the rest of the story.
