Lo and behold the new Tactical Marines. First spotted by us on Deep Strike Radio's Facebook page, we're finally getting a look at the updated kit. Notice that every marine has a unique leg pose. It also seems that the bolter poses are slightly more dynamic as well. And for those keeping track, there are some MKIV legs in here, too. It would seem we'll see the whole suit spread across these kits. The helmet can be found in the Vanguard Veteran kit.
Check back here for more, and also check out Deep Strike Radio's Facebook page as well.
Edit: From an anonymous poster on 4chan's TG board, we now have picture proof of the reloading marine pose!
