OK I love gadgets and have used USG software that is speech related (Dragon Naturally Speaking) but ..........
As a Soldier today you already have a lot of items that you carry and need on the battle field today. Why do I need to get wired with another. They did not show the item and I can only imagine that it is a little case with mic's and a wired camera (another cable harness to put on). I assume that with this I just talk and it paraphrases into a salute format info as they mentioned. Well what if it is on during other activities like #$$#^#$ at your team mates or your interview with a guy who just tried to blow your head off. It might record a bit of info that may not replay well back in the rear or if you are injured higher gets it and reviews it and opens a Article 32 on you for a perceived misconduct that they perceive.
I have found that my little digital recorder worked well to make notes at the right time and I prepare the info later when you return from the Opn and stand down/Debrief. Also nowadays everyone has a little digital camera so the pictures are solved. Now that I am in a LEO job I understand their mindset ref recordings. When the buy-bust starts going bad and the Cav starts coming through the door some one always trips over the power cord which turns off the recorder.
This could save you a lot of heart ache later. There are too many ACLU types that would love to rake you thought he coals. Just look at the 2 SF guys from ASTAN on their Article 32 that is going on. You bet that if this device is fielded that you will not have access to download or review Just like LEO's and their car cams. Big brother (Higher) wants control because he does not trust you. Just my thoughts.
Some time low tech is the answer not lets wire everyone up and play war games. Sure Lockeed Martin wants to sell it, I deal with them all the time and they are only in it for the $$$$$$.
