<p>A protective headgear assembly for use by personnel required to use sighting devices in which a close-fitting helmet (10) carries impact-resistant, energy-absorbing material (36,38,40,42) over that portion covering the wearer's nape, crown and side head portions over the ears but which is free of such material in the frontal portion which covers the wearer's forehead to permit the wearer to bring his eye into close proximity with a sighting device. A separable body (126) of impact-resisant, energy-absorbing material is removably positioned over the helmet frontal portion (70,72) by detachable fasteners (140,142) which secure the body to a soft cover (104) on the helmet (10) where the wearer desires only bump protection or by a separable part (184) of a two-part ballistic shell (176,184) attached to the helmet where the wearer desires both bump and ballistic protection. The helmet can be adapted for use by non-sighter personnel by using either a unitary soft cover (104,148) or a unitary ballistic shell (202) to position the separable body on the helmet. <IMAGE></p> |
