The University of Santo Tomas Golden Corps of Cadets (UST-GCC) also referred to as the UST ROTC Unit is a Reserve Officers' Training Corps unit implementing one of the optional components of the Philippines' National Service Training Program (NSTP) in the University of Santo Tomas.

This made UST one of the first institutions to implement the National Defense Act of the Commonwealth Government.

The Rector and Chancellor of Colegio de Santo Tomas, the Most Reverend Father Domingo Collantes, organized a battalion of 200 Thomasian students, ranging in age from 20–22 years, to fight for the defense of the city.

[1][2] After the implementation of the National Defense Act of 1935,[3] the University of Santo Tomas served the country by providing ROTC training for its students.

During the term of President Ferdinand E. Marcos', ROTC implemented a more aggressive, combat-oriented regimen that exposed cadets to small-unit tactics, unconventional warfare, and self-defense techniques.
