Why are you doubling the hitpoints from 2 armor.
1 Armor is a 10% chance of deflect. 2 Armor is a 20% chance of deflect.
I repeat:
At 2x40hp and 2x1 armor, Sov Sniper is effectively a Conscript model with 2x10% armor roll.
At 1x80hp and 1x1 armor, Ost Sniper is effectively a Conscript model with 1x10% armor roll.
That's totally wrong.
1 armour means when a hit is rolled from small arms that hit will deal damage every time
2 armour means when a hit is rolled from small arms that hit will deal damage 50% of the time.
The penetration of all small arms weapons is 1, to work out the percentage penetration chance its the penetration of the weapon divided by the armour x 100
currently armour is modeled in the spreadsheets as effectively increasing infantry HP.
