Now that Faldom has been possessed by Mannimarco... I can make some comments!
Also, arrows did not penetrate armor
Tell that to the French at Agincourt
Bodkin arrows coated in beeswax were very effective against armored targets, which is why England kept the Longbow in use well into the gunpowder age. However, I think it was noted here or elswhere that they were only lethal if they hit a vital spot because their penetration was so narrow.
And on a different note entirely, I don't see anywhere in this guide taking into account the fantasy nature of the world. I mentioned it several times in the Ka'po'Tun idea thread that fighting a war in Tamriel is not like Japan invading France.
Instead, the races of Tamriel all have unique abilities that do not exist with any regularity on earth. You have men capable of shouting entire cities to ruin, great warbeasts that dominate the field while they last, Magic bursting all over the place in an attempt to decimate the enemy forces, or stop the enemies from decimating their forces.
We have overpowered berzerkers wearing awesome armor capable of rending the toughest metals when they go crazy, bad-ass black guys who will keep on fighting even if hell bar's the way, generic white guys that can partially shrug off even the strongest spells, Lizard men that don't need any special gear for amphibious assaults and pack powerful diseases and poisons they themselves are immune to. We also have elves that can turn the entire battlefield into a blazing inferno and continue to fight unhindered as their enemies burn in the relentless heat, elves that can cause all of nature's beasts to fight beside them, and keep a collection of truly horrible monsters that devour all they come across until they are forced to devour themselves, elves with the magika to partially remake the world around them, or bring about highly-localized apocolypses, and cat-people who can strike fear into their enemies with but a glance, as well as fielding a variety of forces, from small spec-ops units, to powerful supersoldiers, and even terrifying warbeasts with the same intelligence of any soldier.
We also have to remember that approximately 1/12 of the population has a given birthsign, which ensures every army has combatants competant in all three tiers (Stealth, combat, and magic), as well as particularly terrifying effects, whether they are divided into birthsign-governed groups, or mixed with each other to keep the enemy guessing.
