What does defense mean?

I'm just curious. I've been reading the units and I don't quite understand the difference between HP and defense in the context of AtWar.

I realized I needed to calculate how many units I should send to any given stack/city in order to win, so that I send just the right amount, but when I tried to get started I realized I didn't have all the info I needed to make the calculations.

Some people have already made the calcultations. Refer to this spreadsheet: https://atwar-game.com/forum/topic.php?topic_id=39894

1) Defence is the damage you do when defending.

2) Hit Points are the points that you lose when the attack/ defence of a unit hit you.

Hit Points (HP) is how much damage a unit can take, a 7 hp infantry can take 7 hits, so if a tank attacks it and rolls higher then 7 it kills it, critical chance is the chance of a critical hit being scored (10 being 10%, 50 being 50%) it adds a guaranteed damage (like a tank has 8 attack, with a critical hit it automatically calculates that attack in its damage output with aditionaly rolling another attack so you can roll 4 and the attack will be 12 all in all).
