Following Saum’s remarks, he awarded Lopez-Martinez the Meritorious Service Medal for his inspirational leadership and his outstanding performance as commanding officer from July 2016 to June 2018.

Lopez-Martinez praised and expressed his gratitude towards the men and women of his command.

“To the men of women of Team 303, you inspire me every single day, it has been a true honor to serve with you as your commanding officer,” said Lopez-Martinez.
