At our last Midnight Rendezvous 3.0 class which focuses on fieldcraft day and night both with and without NV I took a small sniper veil and draped it over a small "F" target.

Even though that particular target wasn't 2 yards off the trail, most of the teams going through missed the target altogether and the ones that did spot it were practically on top of it when they spotted it.

This is the type of target-

And a small sniper veil like this

Made a target sitting out in the open practically disappear to most people's eyes.

Do you have a sniper veil in your gear? Perhaps you should.

I originally bought one of these 20 or so years ago thinking it may also pull double duty as a mosquito net- it does not do that. However you can dunk it in water (or a cooler if your on the square range) wring it out and wrap it around your neck and get a rapid cool down. Over time the more muted and torn up they get, the better they seem to conceal. My original one was shot more than a few times on jungle lanes hiding targets and seems to conceal better with the muted and sorted shredded look.

Waterproof gear bags-

These can range in size from small football size bags to bags large enough to fit all or most of your pack contents in.

"Back in the day" before the internet and before there was a 'tactical gear store' on every corner- we used to use military OD green laundry bags. I remember buying a lot of surplus one time that included some of them. WTH am I going to do with them? I thought. Some were the old skewl canvas/fabric ones but most were the newer waterproof ones. I looked and thought heck I'll line my pack with this. It worked and my stuff stayed dry on many a FTX where it poured buckets of rain.

Wasn't the most convenient option but it worked and they were practically free.

Now I prefer smaller dry bags for specific pieces of gear you want to keep dry versus one large bag for the entire contents of the pack. One of my packs have sleeping bag in a dry bag, change of warm clothes, watch cap, gloves, etc. in another dry bag. When it's cold and your wet, you string up your tarp, get under it and try your darndest to get warm. Having dry clothes at that point can be a lifesaver. Having had hypothermia in the field at least 2X, I try to take this serious.

Finally, what about a small towel?

I added the Snugpak chamois type towels to our packs years ago. Put a little thing of soap in with little bag with them and packed them away. I've used them after washing up in creeks before on long outings. They also work good for drying copious amounts of sweat off of you. A little over a month ago at Reece class at MVT after one of these exercises where we got jumped by OPFOR and had a running FOF battle over a couple ridges, I used one when we got back to the parking area. I got all my gear off and toweled off buckets of sweat. This was the only way I was able to slow

Newer style breathable athletic shirts can be used in the same manner and I've used to towel dry before when that was all I had in my pack. The Snugpak chamois don't add any weight and take up little space, but then again you can't wear them like the shirt.

However I think you could easily catch water in one and get a dual use out of that with it as well.

Gear should have multiple uses in the field.

When we were young we struggled in the field for solutions to many of these issues and largely just 'lived with it'- being soaked in sweat for days, barely drying out when the day was done and in general just bearing through it. I'm too old for that mess now LOL.
