speaking from experience, the biggest advantage a PVS gave me was better land navigation when wandering around or doing observation. when shooting, most of the time you either had one or two team leaders point with the IR laser at something and others would follow it like old school tracers to engage a point target or area, or you would have a weapon mounted optic like a PVS-14 in front of a red dot. the rest of the time, if you're in darkness and your enemy has a brighter background, you're shooting
into the light and you get a good silhouette without needing a PVS, and if it's bright enough you get PID too from outlines of a nearby vehicle or their weapon or hearing any stuff they might say.
before binocular vision was common (and even red dots were common, so early 90's), you would use a PVS-7 for landnav
and an older PVS-4 passive on the weapon mount and before you ingressed, you would use a spare lens cap with a pin hole in the front to zero at dusk at whatever range you expected and just shoot center mass all the time with bursts. you would have to keep the lens cap on too if you had a bright muzzle flash or you'd damage the phosphor tube.
Hop has very strong opinions on optics too
i've heard all kinds of things about optics even from otherwise pretty knowledgeable gun people. i think it's a bit worse these days since a lot of optics are being pushed based on dubiously useful features or because of marketing/branding or because some secret squirrel types supposedly use it so it
must be good, et c. it's the same trap some fall into thinking that gadgets can provide ability/skill/talent vs enhance what you already have through genuine training and regular practice.
