US military forces use MH 139A Gray Wolf helicopters to drop elite troops during operations
The MH-139A Grey Wolf is a militarised version of the AW139 commercial helicopter developed by Boeing and Leonardo to replace the ageing UH-1N Huey fleet of the US Air Force.

The MH-139A Grey Wolf will support the intercontinental ballistic missile missions of the US covering Wyoming, Montana, North Dakota, Colorado, and Nebraska while complementing the country’s nuclear deterrence operations in line with the National Defence Strategy.

The multi-mission helicopter can also be utilised for transporting the US government officials and security forces, civil search and rescue missions, airlift support, National Capital Region missions, and survival school and test support.
