With v2.0 I was not satisfied with the lighter helmets vs Kevlar vs hard armor, so I continued tweaking this past week. Who the hell thought to put some of the ballistic helmets below level 1 NIJ soft armor, anyway? This is at the limits of what can be done using the vanilla caliber value (a poorly named proxy for penetration in Arma 3) and math. The next iteration I'm working on pulls more values from Arma 3 but is still buggy and even more difficult to strike the correct balance. Version 3.0 here mostly does what I want without gripes, even though I disagree with some of the vanilla caliber values (again, not real caliber) in the vanilla ammunition. If I ever succeed with a v4.0, then that will no longer be an issue, either, but without needing to change every vanilla caliber value: e.i., I will not be relying solely on vanilla caliber value to dictate penetration and damage through body armor.
