Defense Industry Daily reports that the Marines are getting a new spotting scope called the Scout Sniper Observation Telescopes (SSOT). The SSOT is a variant of the Horus Vision Leupold spotting scope system designed specifically for snipers.
I was amazed that the M49, the standard military spotting scope, was designed during WWII!
In my personal opinion, optics are one of the two major improvements in firearm technology since WWII (the other being ammunition component improvements). While I am sure the current M49’s exceed the mil specs from the 1940s it is only 20x in power and has no reticle.
UPDATE: According to Allen, a Marine vet and analyst at The Columbia Group, The Marines will be using a standard Gen II Mil-Dot reticle, not the Horus reticle described below.
The Horus Vision Leupold, as the name suggests, is made with Leupold optics, and offers 12.7-38.1x zoom. Its main feature is the reticles. Unlike standard mil-dot these show a 2d-grid which allows for precise calculations of holdover and, in the case of a spotter for a sniper, calculating speed of moving objects.
This promotion video shows how it works. The video is showing the Horus line of rifle scopes, not the spotting scope, but the idea is the same.
Defense Industry Daily has more info and details of the contact awarded to Horus.
