Just as jeeps and trucks replaced the horse for military mobility, the military helicopter has come a long way toward replacing motor transport. Originally used for only high value missions such as medical evacuation, helicopters are now the primary vehicle for air assault and many other military roles.

U.S. military helicopters are usually prefixed with a type designation from this list. However, there are exceptions so this system cannot be called universal:
AH - Attack Helicopter.Carries weapons used for ground support.
When military helicopters were first procured during World War II, they were designated with numbers like R-4 (R for Rotorcraft). In 1948, the U.S. Army Air Force changed the designation from R to H (Helicopter), renaming existing models. On 9 July 1962 the modern prefix system was adopted and again existing models were renamed, e.g. H-19 redesignated UH-19. Helicopters with an X prefix are experimental, with Y prefix are pre-production.
