Call Of Duty Modern Warfare 2
The MH-53 is available as a killstreak perk after a killstreak of 9 (or 8 with the Hardline perk). Since it is used as an armored attack helicopter, the MH-53 is harder to destroy and packs a bigger punch than regular attack helicopters as it features two gun turrets instead of one. However it is also bigger and slower, making it a potentially easier target to shoot down, provided the enemy guns do not shoot you down first. The helicopter is equipped with one set of flares, which will distract any locked-on missile. After the flares are spent, your missile can track it directly. If a missile strikes the Pave Low while turning to follow the flares, it will still destroy the aircraft just as if it had scored a direct hit. Pave Lows seem to be much more sensitive, with regards to enemy targeting, than their attack counterpart. This may be because it can fire from both sides as opposed to just one.
Calling in a Pave Low rewards the player with 300 XP. Destroying a Pave Low gives 400 XP (4000 in Search and Destroy).
