There are two (technically three) ways to roll during a low light op.
1) NODs - helmet or head mount. Mounting to the rifle kinda sucks since you're adding a lot of weight and forcing yourself to hold the rifle up in order to observe your surroundings. Boonie caps are great for concealment and keeping the sun off you - neither of which are particularly necessary at night.
2) Flashlight - works great if you can't afford NODs. Turns night into day in a small space, along with telling everyone around you where you are. Works both ways.
3) No light source at all. Sucks. Don't impale yourself.
Lasers are good but same problem - it will announce your location to everyone. You will not get enough light amplification on target with a laser for proper IDing so you will need some sort of light source (1 or 2). I assume that "laser light combo" means you have a vis laser and vis light, which is good as a minimum.
Low light scopes are better than nothing, but I do not think the cost benefit is worth it. You will probably need a RDS with your low light in order to aim (lol aiming in airsoft) and the RDS may damage your scope.
