V-22 Osprey

Good

The V-22 Osprey is a US military VTOL aircraft used by the HECU and the Black Ops during the Black Mesa Incident. It was used to transport personnel into combat zones.

Half-Life
The Osprey makes its first appearance near the end of the chapter "We've Got Hostiles" (this appearance marks the ending of Half-Life's first demo, Half-Life: Day One). It can also be seen in the chapter Surface Tension where HECU troops are unloaded and fight Alien Grunts. It continually deploys two soldiers every so often.

Half-Life: Opposing Force
At the beginning of Opposing Force, Shephard is transported in a V-22 Osprey through a canyon along with his squad towards the Black Mesa Research Facility until it is attacked by Manta Rays and shot down. At the end of the game, the player is teleported to a similar craft for the G-Man ending sequence. A black Osprey used for unloading Black Ops also appears.

Half-Life: Decay
In Decay, an Osprey is encountered in chapter six, Code Green, where it constantly unloads HECU troops until it is destroyed or the player proceeds further.

Tactics
The Osprey is unarmed and thus cannot harm the player, but sometimes it will keep on deploying soldiers until destroyed. In such cases, the RPG or the Tau Cannon can be used to defeat it. It can also be destroyed through sustained fire aimed at the rotors, though this is generally not advised, being a waste of ammo.

Behind the scenes
The playable Half-Life 2 Beta files feature models and textures of parts of an Osprey, which was to be used instead of the C-130 by Gordon and Alyx to travel from the Weather Control to the Skyscraper.
