Jeremy,
We launched on July 4th this year.
There is a preview feature for each course you can sign in to without fully enrolling. I am not sure if you can see all of the standards but I can tell you what they are. I'll list at the bottom of this post.
Prior experience is the whole point. To qualify for the grey belt, you must be fighting at the blue belt level. No one is going to be able to do that via the internet so you must have been training long enough to have received your blue belt and have acquired enough skill and fought in enough tournaments to have the required victories. There are no time limits or requirements in the program. The standards are the skills and accomplishments.
The requirements are victory. If you defeat ten opponents as a blue belt, you are a decent blue belt level fighter, and that is the standard.
The marksmanship and lifting standards are fairly low on the first few levels. The program is meant to encourage people to train. Most of the Combatives instructors in the Army were already proficient with basic soldier skills, rifle marksmanship, combat lifesavor, etc. So at grey and green, those standards are fairly easy to meet. At Brown, they take a pretty good jump. Still fairly achievable with a little effort, USPSA C/B class shooter, IDPA Sharpshooter. The intent is competence with weaponry and getting people doing real training with firearms in a way the Army system just can't do. The strength standard are the same, They come from
https://strengthlevel.com/. Grey requires beginner-level strength to get people started. Green requires novice-level. Brown requires intermediate level, which is quite high for most people.
So if you have been training for a while, you will be able to go straight through the lower ranks. We have had a couple go through grey and green within the two months the system has been up.
