  • CA sucks
    I have seen references to the protective level of body armor such as lvl IIa, lvl III, an level 4, what do these protection levels signify?

    Just out of curiosity, how much does a mid protection level vest go for?

    They are the ballistic level that the vest will withstand, ie resist penetration. The I is the lowest and it will stop stuff like BB guns, flat-nosed pellets; up through IV with ceramic inserts which stops stuff like standard rifle cartridges (308, 30-06) and I suppose they could come up with something that would stop a 98 pound 155mm, but it would probably suffer from some deformation.
