Calugus was born on December 29, 1907 in Barrio Tagsing, Leon, Iloilo, Philippines.
Calugas was a Sergeant in Battery B of the 88th Field Artillery of the Philippine Scouts when he was awarded the medal on January 6, 1942 at Culis in the Bataan Province. When he witnessed that a nearby Scout gun position was put out of commission due to heavy Japanese bombing, Calugas ran over a 1000 yards across open field, gathered a volunteer squad and put the gun back into commission once again rendering the gun position as an effective means to repulse the oncoming Japanese units.
Calugas eventually retired from the army with the rank of Captain and settled in the U.S. at Tacoma, Washington. He died in Tacoma in February 1998 at age 90.
