(NBC News) More Americans have arrived in Iraq, but U.S. officials say it's to help, not to fight. 

130 additional Marines and Special Ops forces are in Erbil.

The team is there in a supporting role as ISIS militants threaten to kill up to 30,000 Yazidi Christians seeking refuge on Sinjar Mountain, refusing to convert to Islam.
