All three men were highly decorated. In fact, each had been awarded the purple heart medal.

He's originally from Pago Pago, Samoa.
Also killed was 38-year-old Captain Philip Dykeman.
He was the commanding officer of the battalion's fox company and originally from Brockport, New York.
And the third Hawaii-based marine killed was Corporal Marcus Preudhomme.
The 23-year-old was an administrative clerk with the battalion and originally from North Miami Beach, Florida.
