I've seen a 1988 dated L9 SUSAT that's been re-marked L16A1. It has a crosshair style graticule, as opposed to the typical needle type. That aside, it's identical to the L9 in every way. If this is a known production variant it might be worth including in the main article, but I really don't know enough about them to make a good job of it.

One thing; the "unit" in "Sight Unit Small Arms" is presumably just the word unit. But the earlier EM2 also had a UNIT sight, apparently made by RJ Beck of London; the same design appeared on the early X8E2 FN FAL, which was eventually adopted as the L1A1. Forgotten Weapons has a scan of the manual which identifies it as a UNIT sight, but no amount of Googling reveals what UNIT stood for (Something Something Infantry Telescope?). Is SUSAT in fact therefore an acronym for "Sight, UNIT, Small Arms"? - Ashley Pomeroy ( talk) 17:32, 2 November 2014 (UTC) reply

No, it isn't. The UNIT sight used a completely different principle and was never adopted. The U in SUSAT just stands for Unit, as did the U in the earlier SUIT. Fahrenheit666 ( talk) 14:29, 29 February 2024 (UTC) reply

You learn something every... decade. I wonder if UNIT stood for anything, or if it was just a typo. - Ashley Pomeroy ( talk) 17:50, 10 June 2024 (UTC) reply
