Pave Low

History
The MH-53 is essentially a modified version of the CH-53 or HH-53 helicopter, which was used mainly for transport in the Vietnam War. The modifications include forward-looking infrared, inertial global positioning system, armor plating, Doppler navigation systems, terrain-following and terrain-avoidance radar, an on-board computer, and integrated avionics. The MH-53 can be fitted with three guns; a mix of Miniguns or Browning M2s.

The Pave Low can carry 37 troops or 14,000 pounds of cargo. It also has an external hook which can lift up to 20,000 lbs.

Call of Duty: Modern Warfare 2
The MH-53 is available as a kill streak perk after a kill streak 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.

Trivia

 * The MH-53s in Modern Warfare 2 bear the insignia of the US Air Force's Air Combat Command, based in Langley Air Force Base, Virginia
 * The Pave Low is famous for its appearance as the the vehicle form for the Decepticon Blackout, in Transformers, and Grindor in Transformers 2.
 * The Pave Low's appearance in this game is unusual as all the Pavelows have been retired from all branches of the US forces. The CH-53E Super Stallion has replaced it in the US forces; the CH-53E is much bigger and is able to carry more weight than the Pavelow.
