Ozone (Modern Warfare 2)

"I got eyes on them! Here they come! They're in the field to the south-east!"

Ozone is a soldier and member of Task Force 141 featured in Call of Duty: Modern Warfare 2. His primary appearance in the game is as part of the team that raids Makarov's safe house in Loose Ends. Along with Ghost, Scarecrow and Sergeant Gary "Roach" Sanderson, he survives the initial ambush and moves to breach and clear the safe house. The player can choose between one of three breaching points around the house; Ozone places himself at the main floor's side-door deck entrance. While protecting the safe house from enemy forces, Ozone guards the basement entrance from the outside. However, he may or may not be killed in the subsequent fighting, as he is not scripted to die but is not invincible either. It is very hard to keep him alive in this initial position due to the open area in which he is located. Enemies will come from behind him and from the side, outnumbering him significantly. He will only survive the first position if the player assists him.

Once Archer alerts the team to another wave of enemies approaching from the opposite side of the house, Ozone will relocate inside and hold off enemy forces from the front windows. He will stay in this position until the DSM finishes downloading. While he can still be killed at this point, it is much more rare due to the amount of cover he has. If he is still alive when the DSM finishes downloading, Ozone will follow Ghost, Roach and (if still alive) Scarecrow to the extraction point. Eventually he will be killed, either by being shot by enemy forces or by being hit by a mortar round.

Trivia

 * Ozone and Scarecrow are both invincible until Roach plants the DSM. After that they can die at any point. However, Ozone can only survive until reaching the LZ if he does relocate to the main windows (when "fast attack choppers" are approaching the house from the northwest), otherwise his location is extremely vulnerable and will die eventually.
 * It is strange that Ozone knows there is an armory in the basement despite not setting foot downstairs and not being alerted to one by either Ghost or Scarecrow.
 * If Ozone spawns in The Hornet's Nest, The Gulag, Contingency or The Only Easy Day...Was Yesterday he can be killed by enemy fire, but will still reappear as a main character in Loose Ends. However, his death in Loose Ends is canon.
 * In Just Like Old Times you can hear radio chatter from a soldier with the callsign Ozone. This is, however, unlikely to be the same Ozone as Shadow Company is comprised of Americans, and because of his assumed death in Loose Ends.
 * In certain situations in Loose Ends he will change his position to the big windows inside the house (That particular situation is that when Archer reports enemy fast attack choppers are approaching from the northwest, and Scarecrow indicates that he needs help to cover the front lawn, that's when Ozone would relocate to the main windows).
 * He will usually die before Scarecrow.
