Since this mod is no longer updated and you say in one of the discussion threads that you no longer play and mod anymore, let me shamelessly plug Pacifist which might be a worthy replacement if someone encounters issues with SPM No Military Science: https://mods.factorio.com/mod/Pacifist

It removes ammo, turrets, and guns, but not power armor and peaceful equipment like personal roboports. Vehicles are left in the game but without guns.
The tech tree is cleaned of obsolete tech, and military science packs are either removed or replaced with "equipment science packs" (mostly a different recipe)
