I could open it - worked well, but the browser apparently tries to save it without the pdf extension. If you click on the file and choose "save as", you get the saving location, and the file name as a long sequence of numbers.
I just replaced said sequence by "TTVehcBld.pdf", then saved, and I could open it without any problems. May just be a combination of how the forum stores uploads and how the browser saves downloads.
The content looks excellent, btw. I like your approach of costing "spaces" as well as the purpose those spaces take (e.g. a weapon and its gunners). Have you thought about doing an automated spreadsheet based on it? If not, I would like to try my hand at that, if only for private use.
