Giving Intruders a grappling hook and nightvision, and Flashlights (as an attachment) to the Guards

Ideas:

-Grappling hook: Not a futuristic "batman like" grapplehook, the tool is just a throwable that sticks to specific ledges, like windowsills and balconies, and should be like the binoculars, only a certain number per map, and only a few intruders get it;

-Nightvision: Like the grapplehook, only a few per map, and should be usable with the sniper. I was thinking that maybe the binoculares could have and integrated nightvision (the usage of the binoculars makes the user unable to shoot, that might balance things out);

-Flashlight: Like the red dot, it should be a weapon attachment.
