Should be compatible with all armor values, tested once ingame at 125 armor using that mod. It follows the tables https://helldivers.wiki.gg/wiki/Damage#Armor_Damage_Modifiers for head/chest damage% which means possibly light armor (50) is still taking 125% damage. And I didn't test with Vitality Booster but that should work too, all this mod changes is player headshot multiplier from 1.5 to 1.0
