Comment - Note that the 503d Infantry and the 503dBattalions all bear the annotation of THE ROCK REGIMENT. This, of course pays tribute to the retaking from the Japanese of the island fortress of Corregidor by the 503d Parachute Regimental Combat Team, the 3d Battalion of the 34th Infantry Division and all other units who combined to make up what Colonel George M. Jones had designated as "THE ROCK FORCE." | |

Comment - The above reference to the 503rd
Infantry (The Rock Regiment), of course, refers to the present 1996
designation. "The Rock," was to become associated with the 503rd much
later in its history and comes from the airborne assault on the island
fortress, of Corregidor. |

Comment - To make this chronology
more complete it is noted that the unit which was to become Company D,
503d Parachute Infantry was originally A Company of the 504th Parachute
Infantry Regiment, later became part of the 82nd Airborne Division at Fort
Bragg, North Carolina and was reassigned to the 503rdParachute Infantry
Regiment just prior to their departure from Fort Bragg, North Carolina In
October 1942.
On their way to Australia, the 503rd
Parachute Infantry Regiment stopped in Panama to pick up three companies
from the 501st Parachute Battalion. The companies were Headquarters and
Headquarters Company, A Company and B Company. They were picked up to
complete the 2nd Battalion of the 503rd Parachute Infantry Regiment.
Headquarters and Headquarters Company of
the 501 became Headquarters and Headquarters Company, 2nd Battalion of the
503rd Parachute Infantry Regiment, A Company of the 501 became E Company
of the 503rd Parachute Infantry Regiment and B Company of the 501 became F
Company of the 503rd Parachute Infantry Regiment.
