At the moment you do not. One will need to be appointed by your RCO.
So then concept designs are still capable of reaching the upper tiers of deployment as long as its something fathomable for the Halo universe? Im just making sure that I understand this correctly before I invest to much time into a concept design.
405th guidelines may not mirror 343i guidelines - generally speaking we favour costumes that focus on what is possible in game (for example, no mixing generations, such as Halo 3 Mk VI pieces on a Halo 4/5 body set). With that being said, 343i's official stance on 'mix and match' costumes is 'it's all good'. Concept builds fall into a grey area - they're not exactly canon 'in-game' pieces, but if they've been published later as concept art in official media (art books, etc) I personally would consider them viable.
As long as the costume looks well done and has effort put into it, then you'll be graded fairly regardless of whether it's a canon build, a mix-and-match set or a concept build. Despite the grading system being very weighted and biased towards existing rules used by the 501st, we're not the 501st and the emphasis here is not on having every single one of our costuming members deploying in production-grade, game-accurate costumes. We're here to have fun, meet new people and come together to form a friendly community centered around a common hobby - Halo. Don't let the grading rules put you off of doing something fun and unique - and if anybody tells you otherwise, send 'em to me.
In long and short: build what makes you happy. We're not going to turn you away because you're featuring a concept build.

But in Halo 5 there is armor Mark VI and even Mark IV and V. These earlier gen armor were updated and upgraded into GEN2... So while you aren't doing just Mark VI from Halo 3, you can still do GEN2 with pretty much Mark VI.
It's even called Mark VI GEN1 and Mark IV GEN1.
Best bit of advice I can give you is to have lots of conversations with your local Regiment Membership Officer. They are here to help! You are super close to getting added to a Regiment officially but there is nothing stopping you in the mean time from talking to that person. If you want to let me know where you are located, I can help you find that person!
The example I used wasn't meant to be taken as a concrete suggestion, merely as an example. What you need to be taking from this is that we're not going to be turning people away for having alternative builds - they'll be graded just as fairly as if they were game-canon armours. What matters more is that the effort that's gone into the project is of as high a quality as the builder can muster, regardless of whether or not it's mix-and-match.
Just to clear things up here - if it can happen in game it is allowed here. If it CAN'T happen in game, it is not. Mash ups are no different. The base costume minus the mash up paint job etc. must be able to exist in game. That gives us such a HUGE range of costumes that it's proving difficult to find reference but we decided in the beginning that this was the best way to go So, if you can't play a character in game with a Spartan helmet and ODST gear, then it isn't approvable here. If you are applying with a costume that is playable in game but is a mix of different armor versions, make sure to state that in the deployment application to help the DMO's out when reviewing. Again - your best bet is always to speak to your Regiment Membership Officer or to a Division Membership Officer to make sure what you are considering will be approvable.
Evolver79 - applications might be a little slowed down as we review new DMO applications and get that person up and running but I see your application there and it has been started.
