As per Paul's points:
1. I cannot entirely agree with the "green and khaki" only as I feel we should be open to the different variants of Marine Corps uniforms, specifically to the blues variant. We have already set a precedent we the dress blues as worn by Rex Adams, Derek Smith and Rebecca Majoros. There are four variants of the blues uniform ad well as the service uniform.

Enlisted Blue Dress Uniform. From left to right: "B","B","A","D","C"

Enlisted Service Uniform. From left to right: "C", Service with sweater, "B", "A", "B"
That being said,
true, we are not the US Marine Corps, but it is obvious that the traditions of the Colonial Marine Corps are steeped in the USMC. So long as the costume
does not have the USMC Eagle, Globe and Anchor, has any of the established international Colonial Marine logos affixed to it, and is a variant of the service uniform or blues uniform, I am comfortable with any of these to represent us at the parade.
2. There was actually a precedent set this year and we had a Kris Kobus join us and Tony Leach was standing by. I personally don't think there should be
any benchwarmers, everyone with a service of blues uniform should join us in the colour guard... but that's just me. I understand that some of you with blues or a service uniform would rather have fun in the back, so be it.
3. There never has been a specific person holding a flag. We've always relied on volunteers to hold country flags, and we normally have one worthy person volunteer to carry the USCM flag. Kris made my country very proud to carry the Canada flag, and I was quite pleased with this.
Finally, the topic of Aaron Horrocks marching in actual USMC blues.This is a tricky one and I've thought it out for quite a while... so, here are my thoughts in bullet points:
• When I first saw Aaron on the day of the parade, I thought he was wearing a USCM variant costume... although he was not.
• We normally want Colonial Marine costumes representing our group, not an actual uniform. For instance, I would not wear my actual Canadian Forces dress uniform.
• I have personally witnessed the chastising that Aaron received in 2012 by two other US Marines at D*Con nearby the fan table for him wearing a modified uniform. It got ugly at one point. So, as per his regulations, he
cannot wear a modified USMC uniform that had been made into a USCM uniform. There is, however, the possibility of him wearing one of Rook's service shirt with the rifle green pants (either CF or RUC).
• Aaron is technically in front of us with the US flag... a US serviceman with his own nation's flag, parading in the USA. He had received permission to do so by his chain of command. One could come to the conclusion that he was a separate body, parading in front of us.
• I personally don't have an issue with Aaron parading with the US flag in his USMC uniform, however, back to Paul's point #3... if someone would want to parade with the US flag, we should give him/her the opportunity to do so, and then, Aaron would not be able to participate in the colour guard, unless he had an uniform not made of a modified USMC uniform. If not... in the rear with the rest of the combat troops.
Last point: When I formed the combat troops in three ranks this year, it was for the purpose of counting you all more efficiently. You all stayed in a three rank formation, which I found really sexy, for the whole parade. So, if you'd like to stay in that format, we can do this... or else, return to gaggle formation.
