OH

abbreviationStandard termAviation

The military designation for an observation helicopter.

OH stands for observation helicopter, a classification used by the military for light, agile rotorcraft designed primarily for reconnaissance, target acquisition, and artillery spotting. These helicopters are typically smaller and quieter than attack or utility variants, allowing them to scout enemy positions and relay coordinates back to command. Many are equipped with advanced optics, infrared sensors, and laser designators.
