Locklear

"Last time I checked, I take my orders from the Corps- not from some swabbie... Sir."

- Corporal Locklear to the Master Chief

Corporal Locklear was a UNSC Marine and ODST stationed on the UNSC Pillar of Autumn in 2552 as one of Major Antonio Silva's company. His first name is never mentioned.

Summary
He was rarely mentioned during The Battle of Installation 04 or at all in the gameplay of Halo: Combat Evolved but was present in Second Squad which was the squad which survived the Flood on the swamp. He was also among the handful of survivors who fled in a Pelican when the Halo was destroyed. He, Lieutenant Elias Haverson, Staff Sergeant Avery Junior Johnson and Petty Officer Second Class Sheila Polaski hid in the debris field until they met with SPARTAN-117 and Cortana in their Longsword fighter. The Master Chief recognized that Locklear was in a state of shock from the destruction of the Halo, describing him as "an assault rifle with its safety permanently clicked off." Locklear was hesitant to accept the Master Chief's command at first, but was eventually subdued by the Chief's greater authority. He and the Master Chief then developed a closer working relationship over the course of OPERATION: FIRST STRIKE.

Locklear helped in the capture of the Covenant flagship Ascendant Justice, and was aboard when they returned to Reach. He then accompanied the Master Chief to the surface of Reach, where they rescued the Spartans who had survived the fall of Reach. At some point, he developed a crush on Polaski. He was greatly saddened when she died in the Slipspace bubble caused by the Forerunner Crystal artifact.

He assisted the Eridanus Rebels with the repairs they made to the Ascendant Justice during its' stay in the Eridanus Secundus system. During the repair operation, Dr. Catherine Halsey entrusted him with the Forerunner crystal artifact. Halsey knew it was extremely dangerous as it would never allow the Master Chief to return to earth directly through slipspace and that there was chance it would fall into covenant hands. She also knew that ONI and for that matter, all members of the service would place the rewards of the object's slipspace effect above the risks, putting countless lives in jeopardy. She did not even trust the Spartans enough to relegate them with the crystal. She knew that Locklear would destroy it in an attempt to prevent another altered slipspace battle like the one that had killed his crush, Warrant Officer Polaski, and she also hinted to him that the object's destruction was a necessity as if to guarantee he carried out her orders.

As the battle at Eridanus Secundus began, Locklear was ordered to collect supplies from the UNSC Gettysburg. While making his rounds, he decided to destroy the crystal with some explosive he had collected. He covered the artifact with C-7 Foaming Explosive. His judgment was obviously impaired by his bleak situation, and he was very distraught with Polaski's death. Locklear took shelter behind a robotic dolly, but his cover was insufficient. When he detonated the explosive, the artifact was broken into pieces and a brilliant explosion was produced. When the Crystal shattered some of the parts "squeezed" into Slipspace. The humans on board the UNSC Gettysburg recovered some shards and chunks of the crystal, while the Covenant only managed to gather a few smaller pieces.

Locklear's Death
Although Corporal Locklear technically committed suicide, it was most likely unintentional. He was obviously very upset at the death of Sheila Polaski, a Naval pilot to whom he was attracted, but he also said just before the accident that he "wasn't going to die." It is possible that he was drunk, although the book does not specify whether he drank any of the alcohol or not. Locklear had no idea of the radiation levels the crystal produced, and believed that taking shelter behind a robotic dolly would protect him from the explosion.

It is possible that by completely encasing a radioactive material in explosive, that it would compress in on itself, achieving critical mass and produce a miniaturized nuclear explosion. However unlikely this scenario, an implosion-type first nuclear weapon was the first ever detonated during the Trinity test. This is also supported by the fact that "The brilliant flash of sapphire light was the last thing he ever saw." If Locklear actually did manage to create a small nuclear explosion, then he would have been killed instantly, either by a massive dose of radiation, or he may have simply been vaporized.

Traits
Locklear, as described by the Master Chief, had numerous traits that allowed him to escape Halo. The most prominent of these traits was luck. In addition, as with all/most ODST's, he was reckless and had a knack for charging headfirst into a fight with odds heavily stacked against him.

Trivia

 * He is one of the few people to leave Installation 04 alive.
 * The ODSTs' distrust of the Spartans caused some initial friction between Master Chief and Locklear in the beginning, but later on softened to mutual respect.
