The department will be altering their police badges to change its colors, and to contain the seal of the armed forces branch that the officer served under.
Merrimac Police Chief Eric Shears said the idea was suggested by one of his officers, and that the Haverhill Police Department did something similar last year.
"It's definitely a great way to thank and honor those officers that have served...I think it's very important to remember those we have lost," he said.
Three officers in the department served in the military, and will be allowed to wear the badges in the month of May (for Memorial Day) and November (Veteran's Day).
