You also wont be able to see them with the naked eye. Imagine you're on patrol and your buddy drops dead and there was no sound and no visible sign except the crackling from the fire that carved a hole in his chest. War is already scary enough tyvm. Everyone is going to have to wear white or reflective gear.
Okay, hear me out: camouflage. Desert camo for the satellites orbiting between Earth and Mars. Ocean gray for satellites orbiting between Earth and Neptune. And we can get Hugo Boss to design the camouflage for the satellites between the Earth and the moon.
If they are wearing white, all the better to see them, and use a variety of guns on them. Besides, no white is perfect, even when clean, (which won't last long) so the laser would still chew them up.
