It would be crazy if somthing weird if 1 half of the Earth was turned back in time, back to the days of the Sword, NATO would have a problem trying to contain the problem, like 50,000 men attacking a modern day city, it would be mad, yet make an interesting sci-fi/fantasy story.
While not specific to the medieval period, I am quite fond of the shield. The relative safety of a strong mobile wall between me and my enemy quite appeals to me. That, and the idea of running into an enemy and pushing them sounds interesting. Lastly, some of those shields look very fancy.
Then again, my experience with shields is limited to playfighting in elementary school. We made our own wooden viking equipment (mostly swords and shields) and put up a simple play.
Personally I like the halberds most useful of the polearms, kinda a medieval swiss army knife, and if used in cooperation with a squad/company very effective. Just not good for close up work, much more defensive.
