EA08 is capsule g coin. Although I think I won it somewhere.
From what I have read in the AVA forums, its anti sniper round armor. BUT, if you use it with Pointman, it fails. (so there is no point in me needing it anymore)
If you are smart, you will do research the old school way. Buying every vest. And having a friend kill you while benchmarking data. Thats the only way you will know for certain. But, people are all diff.
I get called tank running round naked, with just default items.
