'They are brothers and now they are brothers in arms': Triplets become US Marines together on...

Three new U.S. Marines share a unique brotherhood.

Connor, Matthew, and Griffin Wehr are triplets who just went through basic training on Parris Island.

Joining the Corps is a calling.

"It’s the brotherhood, it’s the challenge, it’s breath the corp, it's the warrior spirit, it’s being elite, it’s our mindset,” Sgt. Marcus J Webb Jr., Drill Instructor at Parris Island said.

A band of brothers, something the Wehr brothers already have.

"I’m very proud to have my brothers here by my side, first in boot camp,” Pvt. Matthew Wehr said.

Their mother, Michelle Wehr, says it took her by surprise when they all wanted to enlist.
