Editing Armor (section)

== Modern Body Armor ==
With modern technology and all it's amenities, a large choices of body armor exists on the market (the NIJ level approved list for body armor products consumes 212 pages on a PDF file, and that's just stuff the manufacturer has paid the considerable expense to have tested by the NIJ instead of in-house). That said it is good to know what levels of protection for both ballistic and melee threats are. The advent of modern style body armour came at the beginning of the Cold War, when military equipment became ever more complicated to handle and expensive to make. These two factors put an incentive in place for the military leaders of the world to invest more resources into the training of its Soldiers, but also to protect this training and money invested into it (as of writing this passage, the cost of the training alone is estimated by the Pentagon to range between 20-40.000 US-Dollars ''per soldier for just basic training''), as well as the outrageously expensive equipment they are carrying. Compare this to previous wars like World War 2, where 90 days were deemed sufficient enough to teach some basic tactics and the workings of an M1 Garand and whatever specialty gear the individual soldier was issued. Point being: The advancements in weapon lethality also made Soldiers much less expendable (ironically enough) than their previous incarnations.

*'''Ballistic threats''' Aka bullets most of the time. Soft body armor (aka Kevlar, UHMW Polyethylene, Dyneema, etc) that is rather flexible, but also vulnerable to high velocity threats. Thus most body armor of that class is relegated between II to IIIA. From there on out, it's hard body armor, which usually consists of some sort of metallic (usually steel, but titanium and high-strength aluminum are options too), ceramics, and composites. NIJ Standard III to IV stop those threats. Technically, though only rated up to 30-06 AP rounds (IV), some plates of body armor offer higher than IV. Some have even shown to stop a .50 BMG round, though the likelihood of one surviving such a shot from the sheer force of it hitting them even without going into them is still in question. Particularly when that burst of energy can still rupture organs or shatter bones. Standard helmets only go up to level III.
** Since some common threats are ''just'' above certain ratings, like 55 grain 5.56 from a 20 inch barrel penetrating level III or 5.7 pistols beating most soft armor, the NIJ system is currently undergoing an overhaul. While most western countries use NIJ rating standards, at least as a secondary, Russia has its own, completely unconnected, system for rating armor.

*'''Stab threats''' Protects against low speed, high mass stabbing objects (aka knives and maybe some small swords).  Stab and piercing vest should not be trusted for higher level threats such a two handed weapons such as an pickaxe, sledgehammer, axe, spear, and even affixed bayonets. Even a knife in the hands of someone who can put an unusually high amount of force into stabbing can defeat a stab vest. However it is still great for stuff people would likely to conceal where rapid quick jabbing is likely to occur. Of course there is probably protective gear such as riot gear that could be more withstanding of heavier two handed threats, but it's likely best to not take a pickaxe to the chest in the first place.

Overlap between the two categories is minimal. Metal ballistic plates will stop knifes, though said plate covers minimal body area and is typically heavy. Soft armor is one or the other, though one could be worn over the other at the cost of bulk.
