Halo's Military Accuracy

Dear 343 and fellow Halo fans,

I’m a really huge fan of Halo, and I most of all enjoy the Halo story line.
But while viewing different scenes in Halo: Combat Evolved Anniversary Edition I noticed something peculiar. And what I imply when I say peculiar is the way the soldiers and Keyes were saluting. If you look back at Halo: Combat Evolved, Halo 2, Halo 3, and Halo: Reach all of the marines, ODST’s, deckhands/crewmen, etc… all saluted with the bottom part of their arm parallel to the ground and their hands in a karate chop type position, in other words straight, and their index finger touching at the rim of their helmet, officers cap, or their index finger touching the end of their eyebrows; while they maintain the position of attention and their palm face down. but when I played Halo: Combat Evolved Anniversary edition they were saluting with their palms showing, which indicates the UNSC has lost a declared war. Not only that, but in the others games, like I’ve pointed out, the other Halo games had the palms down salute. I know 343i is trying really hard to please all of the fans in the Halo Universe, and they put a lot of hard-work into making us happy, I just wish that they study military bearing, radio chatter, uniforms, and just keep it looking sharp military accuracy wise. You guys really did impress me and made Halo :Combat Evolved look fantastic, but as a fellow Halo fan I ask of you to please look into my concerns.

Sincerely,
Combat Slade x2
