The OPMOD battle mug. Looks like the final product of some armorer that got bored, I guess it gives you the ability to drink your beverage of choice and a place to put your carrying handle when your rifle is fitted with an optic sight and vice versa. You could also use it as storage for all kinds of things.
It's pretty cool, has that "high speed, low drag" factor, but yet I think for consuming various liquids the ol' canteen cup might edge it out because of it's ubiquity, cost and portability.

...but I tend to gravitate towards vintage stuff. When I was in the Corps (back in the mid to late 90s) I used a 70s era cartridge belt. I also stuck with the old ALICE H-harness (All Purpose Individual Carrying Equipment, designed in the early 70s) over the relatively new (at that time) multi-pouch Load Bearing Vest (see Fig. 1).

What I liked about the old cartridge belt was that the clasp was a metal tab that hooked into a metal "loop"(see figure 2) . I was easier to take on and off than the plastic fastener of the modern belts. (see figure 3)
Here is an illustration of the style of harness and cartridge belt I used.

Here's the illustration of the cartridge belt I didn't use, or at least I quit using when I got to the Fleet.

I was old school.
The ALICE system of packs and gear was phased out shortly after my enlistment ended. From what I understand it's still in limited use, so it's probable that there are/were some Jarheads running around Iraq and Afghanistan in the old harness... I digress.
