You understand correctly. But the military keeps buying our equipment from the lowest bidder. IMHO The issued med bag is better suited for a humanitarian mission where the possibility of moving quickly aren't as high as a combat mission because the interior pouches are not attached to the actual pack and would fall out when attempting to move from one casualty to another with out zipping the entire thing closed. As well I find that I can't organize the bag as to what I like to use properly with a bag like the ctoms or a 5.11 or even a larger Camelback. I ended up using a 5.11 rush 72 pack that was even better then the designated med bag.
