MARSHFIELD, Mass. (WCVB/CNN Newsource) — A Massachusetts mother is bracing herself for a dramatic change as her triplet sons prepare to leave the nest. All three have decided to join the U.S. Marine Corps.

"I never thought in a million years that would happen," said Michelle Wehr, mother of Griffin, Matt and Connor.

Over the past 18 years, she has watched her boys grow from preemies into young men and each decided to serve their country.

"I didn't really have any plans for after school, so why not the military?" said Griffin.

"I just saw them doing it and I thought it was just a good opportunity," said Connor.

All three will graduate from high school this spring before heading out to basic training in Parris Island, South Carolina.

"I'm going to ship off, like in July, going to boot camp for 13 weeks and after that, I'll be going aviation support," said Matt.

While they're all going to join the same military branch, the law will keep all three brothers from being deployed in the same area.

They aren't the first members of their family to serve. Wehr said another of her sons served in the U.S. Army, including a tour in Iraq.
