PORTLAND — The Portland Sea Dogs are scheduled to host 100 Maine military service members, veterans and their families on Sunday at Hadlock Field.

The campaign, “Invisible Wounds of War,” helps raise awareness of the Boston Red Sox Foundation, as well as the Massachusetts General Hospital Home Base Program, which provides clinical care and support to service members, veterans and families affected by combat-related stress and traumatic brain injuries.

First pitch against New Britain Rock Cats is scheduled for 1 p.m., with pre-game ceremonies slated to kick-off at 12:25 p.m.
