Technically speaking, you
do need IR lasers to aim with NODs. It's practically impossible to get a sight picture with NODs on, especially during a firefight. You'll probably end up damaging the NOD or accidentally flipping it up when it bounces off your upper receiver.
This is how you hold your rifle with NODs (you look over the sight and aim with the laser):
And you don't keep your lasers on, you implement light discipline, turning them on to aim, fire and then turn them off with the pressure switch.
That's not a good solution either. You need NVGs to see around you, for situational awareness. You can't just walk around looking through your mounted optic all the time. And projecting the optic's image on a display is also very sub-optimal. What you want is a panoramic NVG paired with IR lasers.
There's no point in arguing about this guys... This is just how it is and you should want the PLA to have this paired solution.
