I was asked about this and figured it would be a slam dunk easy post. Everybody likes gear and writing about what I know is just too easy. Wrong, the thing is that when you are so used to something it is just what it is, as opposed to significant or noteworthy. If asked a very specific question about gear I can talk for a long time but looking at our whole organization is difficult because it is what I am used to. In any case I will do my best.
Slings- Almost everyone uses some form of a two point sling. Those who do not go with the generic issue two point typically purchase an adjustable two point sling. There are so many makers and models to choose from that you rarely see the same one twice. No clearly defined trends except two point adjustable. Once in a blue moon (less than 10%) are one points with a few of the two to one type floating around. Some folks who carry M16’s still use the three point but that is mostly because they are issued.
Holsters- The Blackhawk Serpa series is heavily represented and has a distinct majority, I would estimate almost 2/3rds. The rest is split between Fobbit’s with shoulder holsters, various other kydex type holsters, assorted leather and nylon jobs. Some quality products from name brand companies and some generic poorly made junk.
Knives- Almost everyone carries some form of a one hand opening type folder of some make or model on their person. Most are midsized 3-4 inch blades and made by major manufacturers such as Gerber, Spyderco, SOG, Benchmade, etc all. Whatever happens to be selling in the PX/ Clothing and Sales had a slight lead but in terms of knives we are totally all over the place. Of the remainder a few carry piece of junk one hand opening folders, a few carry big (5in+) sheath knives and there is a totally random tiny minority like me and my medium/small belt knife. You see a few more sheath knives attached to body armor or kit but not too many. However I would wager almost every soldier has a decent sized knife (often a KaBar) in a duffel bag or a tuff box.
Multi Tools- Everybody has one (if just because they are issued) and they are usually Gerber’s because that is what sells at the PX and is issued. Some live on belts, others on kit and most in rooms or rucksacks.
Boots- Not as many Danners as a few years back. Maybe it is that we are spending more time in hot climates or maybe that the Army is finally issuing some decent kit to us so folks don’t need to go out and buy that. Lots of light boots with soft soles are worn by Infantry and SOF guys. I wear Altima ExoSpeeds though I have heard the new Nike’s are nice and some folks like Rockies or Oackley boots.
Socks- Some folks wear various commercial hiking type socks but more just use the issue ones.
Bags- The Army really got it right with the new small framed molle ruck. It is an awesome 72 hour type bag. This saves young soldiers a $150+ purchase that was almost a requirement to function and I am happy for that. You still see the odd Blackhawk or Camelback or Tactical Tailor type 72 hour bag carried by someone who has been around more than a couple years though.
Belts- People either wear the standard issue tan belt or go out and purchase a riggers belt from somebody or another. All the ones that are not Chinese junk are functionally equivalent as far as I can tell. For those carrying a holster a stiff riggers belt is very helpful.
Cold Weather Gear- Thankfully again this is an area where the Army has gotten their act together. Soldiers do not need to go out and spend hundreds of dollars any more for the cold weather stuff they need. We are issued lots of fleece, gore tex and thermal clothing to stay as comfortable as possible.
Water carrying- Most folks have a camelback, generally issued but you see an aftermarket pouch (typically the better more molle compatible one) occasionally.
As a disclaimer I should note that products sold in our clothing and sales/ PX get a huge boost in purchases and thus use. Young soldiers often do their shopping within walking distance and because of our busy work hours (and laziness) many folks just get what is convenient. This accounts at least in part for the trend towards Serpa holsters and a Gerber multi tools.
To be honest I can’t really think of anything else but if you have a specific question I can probably go into a lot more detail.
