Healy

Petty Officer First Class Healy was a Corpsman of the UNSC Navy. He was attached to Staff Sergeant Avery Johnson's First Platoon. He provided medical care to the recruits of Harvests Colonial Militia as well as the two SSGT instructors. During his first few interactions with SSgt Johnson, the SSgt saw Healy as another undisciplined Navy squid trying to hide from the Innies as well as being a joker, trying to make his comrades laugh. Healy would later prove his worth during the first contact and battle with the Covenant, providing medical aid to many of the conflicts' wounded.

It is uncertain what happened to Healy after he evacuated off of Harvest or what further battles he participated in. It can be assumed that he took his new found knowledge of the damage to human body that Covenant weapons have back with him to prepare better techniques in treating the injuries.
