5 Years Enlisted Army NG Infantry, soon to commission Mechanized Infantry. As an Infantryman, your Ruck is your house. It's an important investment. The USGI ruck is unfortunately wholly insufficient, and it's common for Enlisted and Officer alike to consider a privately purchased Rucksack. I previously tried Tasmanian Tiger, and have looked into Mystery Ranch, but the Eberlestock Terminator fits my needs more perfectly than any other rucksack ever has.
Pros:
-Plenty of space
-Good seperate compartments to aid in organization
-Separate back compartment for water bladder, gun sleeve
-Comfortable. Feels like the "I used to drive a cadillac, now I pack it on my back" cadence come true.
Cons:
-Needs more velcro on the exterior for Identifier/Morale patches. I bought patch panels from Patch panel and Molle'd them to the top and front of the ruck
-Very rigid molle webbing on the back of the ruck (Where you can adjust the height of harness system) can dig into your back
-A bit taller than USGI ruck, can sometimes cant to a side if not precisely balanced
