Open the editor and place 2 units down - one OPFOR and one BLUFOR. Add the following commands to their init:
this setCaptive true; this unassignItem "NVGoggles"; this removeItem "NVGoggles";
Preview the mission and you'll see that OPFOR still has their NVGs yet BLUFOR does not. If you are the BLUFOR player you can still turn your NVGs on even though you don't have them.
