Then you're not looking hard enough because they're clearly there. Both of them have the exact same shoulder pads. Both of them have the exact same blue streaks on their armor (the outlines of said blue streaks are the exact same on the shoulder pads). Both of them have the exact same antenna. And both of them have the exact same color armor.
I don't see any similarities. And I doubt both Macer and Tanaka are here, with Romeo and Buck being way more likely. I do not think it is anyone from Locke's team.
I'm pretty sure that's the white spartan from Locke's team. The armor is identical if you look at it and compare them.
Well, it isn't Palmer, anyone from Majestic, nor Locke (nor anyone from his team), because the armor is none of their's (just look at the shoulders), so who knows.
Assuming this hasn't been posted yet, Dark Horse's official website released the cover art and description of Halo Escalation #21! Hyyype!!That helmet looks epic. I wonder who that Spartan is. :D
I'm more curious as to who the "powerful new combatant" is. I'd like to assume it's not talking about the Sentinels (though I am glad to see they're going to be in the fight as well!).
Same shoulder pads, same foot armor, same blue streaks, same antenna, etc. And I'd bet my money on it being Tanaka meaning the red spartan on Locke's team is very likely Macer.
I decided to highlight a few of the similarities.
If you still can't notice the similarities then I can't really help you. Either way, Buck wanted time away from Romeo and his old squad in New Blood, so I don't think it's at all way more likely. I think it's much more likely that it's Locke, Buck, Tanaka, and Macer. It fits with 343 saying there would be plenty of strong female characters in Halo 5 and it would also be two males and two females which would mirror Blue Team and I think that's what 343 is going for.
No need to be rude about it, I just do not see the similarities. First, the helmet looks way off. It may share an antenna but not much else. The shoulder pads are completely different, with the top part of the comic one being more flat with a dip in the middle, while the one from the Halo 5 Guardians poster has a much different design.
And Macer seems like a bad choice to add, because she was not even part of the UNSC / ONI two years before this. It just does not add up.
I think that Buck and Romeo will not be separated, even if he wanted some time apart. He requested that they be transferred to a new team where he was not the leader. That seems to hint that they would be together still.
Blue team has two female members, and having Tanaka will be a third. Halsey a possible fourth. Plus I am sure there will be more. (Petra hopefully? :D )
