Belgian M51 Helmet
The Belgian M51 helmet (officially designated as the T-21) is an iconic steel combat helmet used as the standard issue by the Belgian Armed Forces (ABL) from the early 1950s until the 1990s. It is a direct European variant (or "clone") of the legendary American World War II M1 helmet.
Key Features and Design
- Two-Piece System: Exactly like the US original, the M51 consists of a heavy steel outer shell and a lightweight, removable inner liner.
- Material: The outer shell is made of a durable manganese steel alloy.
- Inner Liner: Early 1950s models used resin-impregnated cotton duck fabric liners. Later versions (from the 1970s onward) featured adjustable molded PVC or thermoplastic liners.
- Markings: Many original issue helmets feature a small Belgian flag (decal or paint) on the left side of the shell or liner. Well-known Belgian manufacturers include UMAL and VDN.
Colors and Variations
The helmet was produced or painted in specific colors depending on the branch of service:
- Olive Drab: The standard color for the Army and operational troops. It was often worn with a camouflage helmet net or a cover in the famous Belgian "Jigsaw" pattern.
- Navy Blue / Dark Blue: Used by the Belgian Navy and the former Gendarmerie (Rijkswacht) for riot control and law enforcement.
- Light Blue: Highly common on the military surplus market. While often mistaken for UN (United Nations) helmets, this specific light blue color was primarily issued to the Belgian Air Force and the Civil Protection (Burgerbescherming).
Current Status
In the mid-1990s, the steel M51 was phased out by the Belgian military and replaced by modern Kevlar combat helmets (such as those made by Schuberth). Today, the M51 is a popular, highly affordable collector's item in the militaria community and is widely used in historical re-enactments.
