A military or police helmet system 20 has a flexible plastic liner 24 mounted to the wearer's head 26 by a strap assembly 28 . A ballistic shell 30 with a shallow front wall is fastened to the liner 24 and an eye shield assembly 32 is pivotably mounted to the liner for movement between a deployed position and a retracted position between the shell and the liner. The liner has a rear segment connected to a cap segment, with cut-out slots which allow the liner to apply pressure to the wearer's neck. A chin strap is slidable on two stiff side straps which have curved segments allowing the chin strap to move with the user's jaw. A protective face guard assembly 34 engages with the liner and has openings covered by resilient sheets which permit a marksman feel a rifle stock through the face guard.
