If you need to stack cases of rations on a pallet, this is the way I learned to do it in the army. One day when I ws in Germany I helped the mess sergeant, actually a Specialist, and her husband, a lower ranking Specialist like me, stack cases of C-rations on a pallet. I don't remember ever pulling KP duty the years I was there because I couldn't be spared without hurting the shop and our customers. But somehow, I had enough free time and was sent over to the mess hall to help my friends load a pallet, or pallets.
They showed me how to stack what they called an 8-block (not 8 in an en bloc clip
) on a pallet that was too small to hold 9 cases per layer. I can't find the term 8-block online anywhere, but can remember that little bit from 40+ years ago. The 2 rows of 3 cases each were stacked right to the corners of the pallet, and the 2 turned sideways went to the end of the pallet, but not the sides. The next layer was stacked exactly the same, except starting from the other end up to the corners. You keep alternating direction until the pallet is full. The "joints" between the cases are staggered just like bricks in a wall and won't fall over before you can get them banded or wrapped. You could crawl around on them if you were even somewhat careful.
If you're storing cases of anything at home you can do the same exact thing. It doesn't matter if you're stacking stuff on a pallet, or just filling an available space on the floor of your house or garage, this will still work. And if you have room for an extra row on the side or end, you do the same thing, making sure to stagger the joints like dry laid masonry. You could add 3 to the end and stack 11, or add 3 to the side to stack 11 that way. Since I couldn't find an illustration of this particular pattern online, I made my own with Microsoft Paint using same sized rectangles that gave the same approximate proportions. If yiou have cases with even proportions of width to length, like 2x3 or 2x4, there are several ways to stack them according to patterns you can find online. This is for odd numbers of things that are much harder to stack properly if you don't know this little trick. It will work with cases of bottled water too, and with more people stocking food and water, this could really help.
