If you hear a whop, whop, whop overhead in the next couple weeks, rest assured there's (probably) no invasion.
It's a flock of eight MV-22B Osprey tiltrotor aircraft from the Marine Medium Tiltrotor Squadron 263, based out of Marine Corps Air Station New River, N.C.
The unit is coming here for a training exercise at Fort Carson through Sept. 24, the post says in a news release.
The exercise will allow VMM-263 to train for expeditionary operations, ensure deployment capabilities and test training readiness in the unfamiliar environment and terrain of Colorado.
The MV-22B Osprey blends the vertical flight capabilities of helicopters with the speed, range, altitude and endurance of fixed-wing transports. The effectiveness and survivability of this versatile aircraft has been demonstrated during land-based operations in Iraq and Afghanistan and sea-based operations in Haiti and Libya.
The MV-22 has been supporting the Marine Corps continuously since October 2007, in extreme environmental conditions during 11 combined deployments to Iraq, Afghanistan and aboard amphibious shipping.
VMM-263 will train at both Fort Carson and Pinon Canyon Maneuver Site. The training will include aerial gunnery on Fort Carson. When traveling to PCMS, VMM-263 will fly at least 1,000 feet above ground level and fly in airplane mode to help mitigate noise and vibration.
