Technical Manual for Night Vision Sight for Crew Served Weapons 9927, 9927A and according to the manual, 9927B.
Given the media intensity given to the Corona or Wuhan virus, there seems no reason to have posts on that very specific subject in several forums Accordingly, all of those posts will be moved to "Headlines". All new items on that subject should be posted there as well. This notice will expire on 1 April, or be extended if needed. Thanks, folks.
