Army Composition/Soldier Types

[Boromir88]

First I would like to say just a stunning analysis on the composition of armies, and I would hate to nit-pick on something. But remember the fact that we actually are nit picking is a testament to the amount of research and overall good analysis.

(Boromir’s sword stroke bounced off the cave troll’s hide),

The cave troll in Moria was an invention by the movies. It was a large orc leader the Fellowship fought, but the point is pretty accurate. Because Boromir's blade was notched as he hit the black orc leader and he was driven back. Then the orc ducked under Aragorn's blow, so this orc leader was strong and agile.
