Kenyan-born runner Hillary Bor won’t be content with just wearing the red, white and blue at the Olympics.

He’s willing to protect his new country, too.

The sergeant in the U.S. Army heads to Rio this month while his unit — which includes his older brother — is already deployed to Afghanistan. Bor stayed behind this time, but it could be his turn soon.

That’s the reality for Bor and three other runners of Kenyan descent who’ve taken a unique path to the Olympics through enlisting in the Army, earning U.S. citizenship, training with the military branch’s World Class Athlete Program and making Team USA.
