I've been out of 40K for...3 editions now, or so. I've been pretty much an exclusive DE player since around 2002, and 6th and 7th weren't fun for my preferred play style, and 8th didn't do much for me. I'm hoping the new codex will bring back my interest in playing (I actually started playing with Rogue Trader back around 1988 or so).
My question is simple, but it might be based on a misunderstanding of the rules.
With Wyches, once you get into combat with them, how do you prevent the target unit from pulling out their ubiquitous pistols and shooting the girls off the table, even if they are within 1" of the Wych unit?
