Thanks for the reply, especially the reminder that data sources may be unavailable, especially in today’s warfare where the assumption seems to be that the data’s collected from computer based systems so everything will be available. Judging from the performance of many major utility companies to transfer data between different systems, I actually think those looking back from two hundred years in our future, will probably be having the same discussions we are here.
Your comments also made me ponder one humorous question:
If a unit had been on “a long weekend carousing”, what allowance would a commander have to make for their tactical movement rate on the next day? 🙂
