I just picked up a working replica pair of pas/14's off www.delmarvatactical.com/index.php?main_page=product_info&cPath=5&products_id=3&zenid=5hsdcmul9nr4q84dbbmspggd56And was wondering if any one else was going to be rocking any type of night vision that is going to the Grayling gig? It is going to be a handy (potentially) thing to have for any night games. I was thinking it will help out for any Frago's that we get for the night mission stuff. I guess I was wondering, figuring on it being pretty lit up how necessary they might be or not. I am sure they will have quite a bit of the place well lit but how well lit are the buildings inside? Hopefully these aren't pointless.

If by night vision you mean a really bright flashlight that is going to get me killed more than help me, then yes. Atleast the strobe will be an effective counter to nightvision.

Ha ha ha. I mean I was thinking along the lines of when players are sleeping or taking a break to keep from getting snuck up on or sneaking around a group of opfor. Not necessarily using it during a fire fight because yes a flash light will def. suck to the eyeball.

Ogre strobes will have very little effect on anyone using gen 2+ Or gen 3 nvgs like myself. There is this nifty feature called autogate that keeps my nods from white-washing. Your strobe function just makes you a much easier target to engage when trying to counter these devices. And if your even more high speed like some of us you would have purchased a laser light interference filter as we'll to keep those pesky lasers from burning up our very expensive image tubes. So please if you can try not to point lasers or flashlights intentionally in the face or eyes of anyone especially those using nods as this could cause a potentially unsafe situation and not to mention possible property damage if it was deemed malicious and purposeful. Just remember safety is the first priority. And to answer the earlier question about lighting, from my experience at multiple modernized MOUT sites across the US and abroad, many if not all I have trained at are energized buildings and are lighted in main corridors and common areas. Some even had lighted avenues and streets to replicate an urban environment, but then again many of the newer sites also had red lighting for monitoring teams in low lighting conditions. What lighting is actually turned on is up to the range operators. I doubt we will even need nods, as a carefully used flashlight will pretty much get you through anything, but to each their own I suppose.

^^No offense, but LIF filters do absolutely nothing to protect your unit against lights or any sort of laser system. Whoever told you that misinformed you. You're definitely right on the ambient lighting. You can look at one of the overhead views and see that there are at least a couple dozen streetlamps that I'm sure the Major will have running during the night as usual. It won't be difficult at all to navigate within the MOUT. Just to be safe though, if you're on Green you should definitely pick up an IR strobe and run it during the night...for safety sake.

How much are IR strobes?

cqbr I believe you and I are both right and wrong about the LIF. It is hard to get technical information about it as it is still listed as Secret, but from my research and use in the field Im pretty positive, but could be wrong, that these were made to protect expensive imaging tubes from getting immediately burned from intense IR and NIR targeting lasers and IR equipment within a specific spectrum 720-850nm+? Now either the government has produced a device which does nothing (wouldnt put it past them) or it does work. I will keep mine in just to be safe, and if anything the LIF and my Lex keeps my glass a little safer. I would also love to see any information or links you could provide me that test, ordocument that it does or does not work. Thanks bud, not being a jerk or anything, just curious now.

LIF filters do protect against lasers. That's what they do... Most on the market are for blue and green wavelengths. (450nm and 532nm) You can get them IR as well. (720nm ish)

Viper I think the LIF that I had the misunderstanding about only keeps image tubes from immediately burning due to IR and VNIR. I would imagine green lasers would eat LIF's and tubes for breakfast if prolonged exposure was a factor. But as always I could be wrong as the specifics of the usgi LIF's are still shrouded. But those visible LIFs you speak of sound very cool but would probably be like sunglasses on my pvs14's haha.

First victim right here ---> In all seriousness though, they usually run between $40 and $50 on Ebay. I picked one up for hiking purposes. Fun little devices, especially to blind the wife with when she least expects it...

Or you can get a firefly jr. for about $20 on there also, it just plugs on top of a 9v battery.

But those visible LIFs you speak of sound very cool but would probably be like sunglasses on my pvs14's haha. Right, kinda. A green laser won't hurt the LIF. It's just a piece of glass. Tubes, maybe? Depends on power and exposure time. An LIF is basically a crappy notch filter for the IR band of wavelengths. We use NF's here to protect camera systems/peoples eyes from nd:yag and CO2 laser wavelengths in our laser processing equipment. We pass visible light to the user and block the laser wavelengths. Below is an example of a NIR Notch Filter and it's coating specs. Note how it drops to ~0% around 830nm (a common NIR laser band) Click MeThis would be like an LIF except that the LIF doesn't completely block out the wavelengths. Instead it would allow some small percentage through, ie. sunglasses like you suggested above. And you can get them for whatever wavelength(s) you wanted. An IR LIF would dim the picture you see, if say your IR illuminator was too bright and not adjustable. Or it may drop the power level of an IR laser that someone is shining at you to a level that won't damage your NOD's if you catch it directly at you for a second.
