The unit was reconstituted 1 May 1936 in the Regular Army as Troop D, 16th Quartermaster Squadron, an element of the 1st Cavalry Division.

[2] Troop D was moving with the division when it earned its initial first designation, "First in Manila" during the campaign to retake the Philippine Islands.

As the Japanese will to fight evaporated on the clouds of Hiroshima and Nagasaki, Troop D marched into Japan when the division achieved its second motto, "First in Tokyo".

In the invasion of North Korea, the First Team’s third accolade, "First in Pyong Yang" was added to the battle honors of the division and its quartermaster company.

[3] Upon its return to the United States in 1971, the 15th Supply and Transport Battalion and the 1st Cavalry Division moved to Fort Hood under the TRICAP concept.

In March 2004, the 115th Forward Support Battalion deployed to the Persian Gulf for Operation Iraqi Freedom II.

The battalion mastered a myriad of new tasks and challenges as it adapted to the rapidly changing environment in and around Baghdad during their year-long deployment.

The unit has a reputation within the 1st Cavalry Division for getting the job done and "Making it Happen," a phrase that describes the hard-charging spirit of the battalion and the men and women who serve in it.
