Swiss M1971 Helmet

The Swiss M1971 Helmet (commonly known as the M71) is a military steel combat helmet used by Switzerland from its formal introduction in 1971 until its gradual replacement by the Kevlar Schuberth B826 (Schutzhelm 04) starting in the 2000s.

Though designated in 1971, it was not widely issued to units until 1975–1976. It replaced the aging M1918 series and the M48/62 model. 

Key Specifications & Design

• Shell Construction: Made from 1.15mm thick hardened steel stamped in a single operation.
• Shape: A near-hemispherical design with prominent flares on both sides and a lower profile than its predecessors to facilitate the use of optical sights.
• Finish: Painted matte dark olive green with a textured finish. Early versions were occasionally produced in black, and specialized white (Medics) or blue (UN) versions exist.
• Liner System: Consists of a metal circumference band with a foam spacer between it and the shell. It features four leather pads connected by a drawstring for sizing.
• Ventilation: Two vent holes are located toward the rear to increase airflow.

Notable Features

• Backpack Attachment: Many units include a specific hook on the rear for attaching the helmet to a backpack.
• Chin Strap: A secure four-point setup with a simple hook-and-catch system and a break-away junction fitting for safety.

Variations & Misidentifications

• M71/90: A 1990 update that retrofitted older shells with a hanger ring on the rear rim.
• Paratrooper Myth: The M71 is frequently misidentified as a paratrooper helmet. Swiss paratroopers actually used the M48/62 or the French "Gueneau" models.
