I completely agree about taking that program with a grain of salt.
However I did find their tour of the positions interesting. Wish I could remember what they called the terrain feature (I'll settle for birm). I found it interesting because the birm was not immediately apparent, but substaintial when they got to it. It seemed like it would quickly become a serious obstacle to maintaining order and formation while traversing the field under fire.
Especially after everything got churned into a mud pit.
Guess my point is that maybe the longbow was a good weapon with even greater potential when deployed under favorable conditions (for it). Perhaps its fame stems from right tool with right user in right place more than its innate supiority or inferiority in lab conditions?
