Thanks for the comment, I appreciate it. Since these were never played with I had no clue. But I know what you mean about the mega blocks because some of my sons Power Ranger sets took a lot of effort to put together and they were part of a set!
If you want military sets best lock and megabloks are pretty much it. Lego has an aversion to the military. If someone else wins they can contact me and I will try to help with instructions.
