The West Roxbury VFW Post 2902 performer the color guard and New Hampshire Army National Guard First Class Sergeant Michelle Lowes sang the national anthem.
Red Sox outfielder Jonny Gomes said he was honored to be a part of the tribute.
"It's pretty cool, just in our profession in general, that we can have a tribute to the military," he said. "I definitely wear [the special uniform and hat] proudly."
The Red Sox also recognized their employees who have served and several Gold Star wives whose spouses died while on active military duty. The crowd at Fenway Park gave a standing ovation multiple times throughout the ceremony.
"It means a lot for all those men and women who have served and are still serving to be able to wear something to tribute and celebrate this day," Boston outfielder Mike Carp said. "My grandfather served in the [1950s]. He holds the forces true to his heart. It's pretty touching to hear what they've been through."
