Yes, the system can be compared to the AoEIII counter system, but without resists; while the armor value of each unit exists in percentages, and pierce, hack and crush are matched by melee, ranged and siege resists, there are two basic differences: these values are not fixed and unmutable (as in AoEIII), but they can be upgraded with technologies, most of them found in the Armory, the AoM version of a Blacksmith. Also, these values influence buildings too, and can be upgraded likewise, with Masonry and Architecture.

As for AoEI, it indeed seems to have an "armor class system", similar to the one in AoEII (e.g the Cavalry unit causes +5 damage to melee infantry, except Academy  units. This means that there must be certain armor classes, as both Broad Swordsmen and Hoplites  are footmen, but only the first will receive extra damage from cavalry.

By the way, I deleted the bugs page, do you mind deleting Voobly?
