These are the Cyberleader and Cybermen from the story Revenge of the Cybermen. They don't have guns because these are the only Cybermen who shot pure death out of the bit where their head lamps should be. These action figures all use the same body, with the only difference being the Cyberleader's black handlebars. Their heads don't move, but if you try and turn them you can pop the head off (as seen in the picture above). It pops back on just as easily and is pretty secure otherwise.
These are also the only Cybermen I've seen with protruding back elements. It makes the Cybermen seem bulkier when seen in profile. I don't know how I feel about this, but it's show accurate, so whatever. Incidentally, I think the way they've designed the hands on these three guys looks kinda weird. Almost like they're about to summon a fireball.
