Governor Janet Mills and Senator Susan Collins were there to thank troops for their service.
69 soldiers from the 286th Combat Sustainment Support Battalion will be deployed to Poland next month.
"You have my unwaivering gratitude for your service." said Gov. Mills. "You are the ambassadors of our nation in doing this service. You are ambassadors of the state. We are enormously proud of you."
LTC. John Wilmont said it's one of the best groups he's seen during his 22 year career.
"The 286 CSSB is an extremely strong and capable unit." Wilmont said. "The source of our strength is our soldiers."
The goal of Operation Atlantic Resolve is strengthen bonds with with ally militaries.
It's not a combat mission, but soldiers said it doesn't make deployment easier.
"Leaving loved ones in your family is never easy one." said CW3 Gerald Kirk. "It's the first thing you think of. For 9 months, you're gone. Your family is doing all the work."
According to Sen. Collins, the battalion is doing essential work.
"When duty calls, the men and women of the great state of Maine have always answered willingly and courageously." said Sen. Collins.
The group is expected to return in January or February of 2020.
