Cubria was commissioned with the rank of lieutenant, making her the first Cuban-born female officer in the United States Military.

She was later reassigned to the 322nd Signal Company, where she worked on secret codes, and on gathering information on the Axis Powers.

When the Korean War ended in 1953 Cubria was given a medical discharge, and was awarded the Bronze Star Medal for "meritorious achievement in ground operations against the enemy".

Cubria's work with the refugees proved to be a significant asset to the United States Army and the Central Intelligence Agency.
