There was some discussion a little while ago on this thread about what medieval "boot camp" was like, and it seems that conclusion was largely that it was non-existent. People seem to have learned to fight from their fathers, uncles, and in the local fencing hall, if they lived in a large enough community and had the time and money.

However, I have hard time believing that any of these sources of training are going to produce the kind of soldier who can march and fight in a disciplined schiltron or similar formation. Even a less disciplined shield-wall seems like it would require practice with lots of other guys with similar kit.

Does anyone have any ideas, or just educated guesses about the training environment for the Swiss and Scottish pikemen and halberdiers who fought in the schiltrons that stood against knightly attacks in the 13th and 14th centuries?
