"Understood, Dragon X-ray. Give 'em hell out there, and good luck."
— Blue-Delta to Dragon X-ray.

Blue-Delta was the codename of a member of HIGHCOM who was present during the Fall of Reach.[1]


During the Fall of Reach, Dragon X-ray, the radioman of an unidentified UNSC ground asset radioed in Blue-Delta for assistance. Blue-Delta warned X-ray that his unit was the only UNSC asset in the area, meaning that any support would take a while to arrive. X-ray was unable to hear Blue-Delta's response due to enemy movement, to which Blue-Delta warned him again. X-ray acknowledged receiving the warning and reported movement again, requesting for support to "soften them up". After being asked for the location of the enemy forces, Dragon X-ray responded and gave him the grid co-ordinates.

Requesting for support again, Blue-Delta told Dragon X-ray that there was no available support in any way apart from the UNSC Aegis Fate. Dragon X-ray inquired whether the Aegis Fate was a space-borne or an ocean-borne vessel, to which Blue-Delta answered that the Aegis Fate was a Frigate-designated "Exo-asset". Dragon X-ray reported to be less than a klick away from the objective, and Blue-Delta ended the conversation by wishing him good luck.
