Canteens are slowly going the way of the dodo as the primary water source for allot of militaries, ourselves included. That not to say that they we don't need them or that they don't work, but there is a better hydration system is out there for the troops. I personally like a combo of Nalgene and Camelbak in my kit but that's just because I've seen cheap camel bak bladders break under stress.
Camelbaks are much better than the standard canteen, because you can drink while moving, and without taking your hands off your weapon, while in a concealed position,
Hand-Free Access â “ Keep your eyes and hands focused on you mission.
Carries More Water â “ Up to 3-Liter capacity, so you don't run out.
Keeps Liquids Cool for Hours â “ Insulated reservoir compartment, so you drink more.
With the CamelBak Hydration System, you:
Protect soldier's health â “ avoiding heat illness by avoiding dehydration.
Be more effective â “ keeping soldiers alert and focused.
Maintain performance â “ dehydration can cause serious fatigue and reduced muscle endurance
Without the bulky canteen banging on their hips, it's easier for soldiers to squeeze into combat vehicles and climb through windows during urban combat. However some models of Camelbak allow you to get hung up on stuff just as easily, but so does the new TV for that matter.
As for the guys wishing for new Night Vision and it related paraphernalia have you used the new AN/PVS-14? The AN/PVS-14 (the monocular) is an excellent piece of kit and in combination with a AN/PAQ-4 or AN/PAQ-2, makes night operations allot easier.
