The H-series is a series of tactical trucks of Hungarian origin. The H-series was developed by Hungarian truckmaker RÁBA in the late 1990's to meet the demands of the Hungarian military. The H-series is externally very similar to the MAN Kat 1 and later SX and HX series of tactical trucks. The designs are unrelated although a lot of MAN components are used and MAN trucks have clearly been a design inspiration.

The H-series comes in three main types that allow for a different gross vehicle weight. The H-14 is a 4x4 design while the H-18 and H-25 use a 6x6 chassis. All members of the H-series have a forward control cab that looks very similar to the cab used on MAN military trucks. This cab design allows for maximum space within space limits regarding train and aircraft transportation. The engine is mounted under the cab and all four or six single wheels are powered. Add on armor for the cab is optional.

The chassis allows for a wide variety of body types and includes cargo, container, tanker and office models. A small crane behind the cab or a pallet or container loading system are optional. The body plus cargo capacity ranges from allmost 8 t for the H-14 4x4 truck to 13 t for the H-25 6x6 truck. All models may tow an 8 t trailer under off road conditions.

The H-series has a good road and off road performance. All members of the H-series feature all wheel drive and high quality automotive components. All models are powered by the same EURO 3 compliant 280 hp diesel engine. This results in a limited power to weight ratio in the heavier models. Therefore the H-25.324 with a more powerful EURO 4 diesel engine has been developed.

The H-series is currently only in use with the Hungarian military. All three versions are used with a wide variety of body types. The H-series remains in production and is available for export.
