As it is nearly identical to untrained eyes in shape to the PASGT, and outside of the Marine Corps it is still called the Fritz helmet or K-pot (due to its resemblance to the German Stahlhelm). Though heavier than the Army's Advanced Combat Helmet, its larger size also offers more protection and is lighter than the PASGT. Featuring a V-neck strap and improved fit, it is much more comfortable than the PASGT. The LWH entered service in late 2003 and completely replaced the PASGT by 2009.
