I've played Dark Heresy, Rogue Trader, and Black Crusade and none of my characters wore any armour less than 3 across thier entire body.
Most of the premade regiments have full flak armour, which seems like solid protection for front line fighters.
My regular gaming group is considering playing Only War and everyone (including myself) are stoked to try Catachans (many Rambos in my group). This leads to a possible problem, flak vests (and helm). While completely in the fluff, considering how important armour can be for survival in this game how do you survive encounters?
Outside of the obvious dodge, parry, cover that any guardsman could do, it does seem like many of the regiments get a little screwed by this.
Catachans, Tallarns, and Mordians (though Mordians are probably content fighting from the protection of their Leman Russ).
If you're currently playing as one of these regiments how do you overcome the dreaded flak vest? Homebrew or otherwise.
