His Bronze Star Medal w/Valor Citation reads:

For heroic service in connection with operations against the enemy in the Mekong Delta region of the Republic of Vietnam from 21 August to 29 October 1968. As Grenadier for the Fourth Platoon, United States Navy SEAL Team Detachment ALFA, Petty Officer Ramos participated in twenty-three combat patrols and operations during which he was often subjected to direct enemy fire. His courage and professionalism were an invaluable asset to the Fourth Platoon in countering enemy forces, against whom he directed extremely accurate and effective grenade and rifle fire. On 10 October 1968, while returning to their base after completion of a twelve hour patrol, the Fourth Platoon encountered intense enemy fire in an area infested by North Vietnamese and Viet Cong communist aggressors. Although he was exposed to a heavy volume of enemy small arms automatic weapons fire, Petty Officer Ramos fearlessly covered his squad's movements and enabled them to extract without casualties. On 29 October 1968, during an operation with Vietnamese Provincial Reconnaissance Unit troops, Petty Officer Ramos was mortally wounded while valiantly engaging a numerically superior enemy force. His devotion to duty, courage under fire, and sense of responsibility significantly contributed to the fight against communist aggression in the Republic of Vietnam, and were in keeping with the highest traditions of the United States Naval Service.
