English: Detail of XL64E5 Individual Weapon cropped from MOD image no. 45162601. The relevant portion of the original image's description states: "The XL60 series of experimental firearms was the first generation of what was initially known as the ‘485 Weapon System’, designed and produced at the Royal Small Arms Factory (RSAF) Enfield, located in North London, United Kingdom. The term ‘485 Weapon System’, so-named for the weapon’s 4.85 mm calibre, was later dropped in favour of ‘Enfield Weapon System’ or EWS, which persisted until at least 1982 but was ultimately also side-lined. Instead, the name ‘Small Arms of the 1980s’ or ‘SA80’ was adopted and remains in use to this day. This term is used alongside the land service or ‘L’ designations (e.g. L85A2). Interestingly, this name was in use from the very beginning by the Ministry of Defence (MoD), sometimes with the prefix ‘Section’ as in ‘infantry section’ or squad. As per the preliminary study and MoD specification, the EWS/SA80 system comprised rifle and light machine gun variants, known by their period NATO euphemisms of ‘Individual Weapon’ or IW for short (today simply ‘Rifle, 5.56mm’) and ‘Light Support Weapon’ or LSW (a term still in use today, sometimes considered interchangeable or overlapping with ‘squad automatic weapon’, or SAW; automatic rifle; and light machine gun, or LMG). Several variants emerged during development which all received their own designations."
