The individual stats that comprise it for each unit are Armour, Skill, and Shield. For instance, Armored Sergeants have defense listed 14 on their info sheet, which is their front melee defense rating. This is the convention applied in the game. That number is arrived at by adding the unit's armor, skill, and shield, which all apply from the front in melee. Armor applies to all sides of the unit, skill to the front and right, and shield to the front and left. Additionally, armor and shield apply (in the same directions they do in melee) against missile attacks as well, while skill is ignored against missile fire. Hope that clarifies the terms and their interaction for you, but of course feel free to ask further questions or rephrase the current one if I haven't covered what you were trying to get at.
Sorry, I meant "skill" instead of "defence" then.
