Unless I miss my guess, you've just described a Wehrmacht Panzergrenadier Regiment, circa 1941 (ie., Operation Barbarossa). The only difference I can see is you're a bit heavier on airmobile troops (i.e., paras/Fallschirmjager)than they were historically. How do you intend to deliver them- helos, V/STOL (i.e, something like Osprey), or something we don't have as yet?.

torm Platoon = Platoon Lance = Company Detachment = Battalion Regiment = Regiment The organization is notably “Mech-heavy”, starting with the fact that you’ve got a Storm Platoon of 6 IFVs, instead of merely 4. They’re also pretty large IFVs, carrying 9 dismounts per (Bradley carries only 7, while I’ve seen no design carry more than 8). Are we talking something like Marine AAVs here? Look at the Infantry Lance: 13 IFVs supported by 9 MBTs – “infantry lance” is right, sort of an evenly balanced Mech Infantry Company. The other stuff is already being done, like pushing Arty assets down as low as possible – a good idea. The idea of 1 Air Assault Detachment/Battalion per Regiment is interesting – don’t know how practical it is, though. No experience in this matter. I think Marine units might be integrated like this, not sure. What we end up with is a good, mobile, armored force with a large dismounted infantry component, making it especially suitable for dense terrain or mobile defensive ops; the relatively fewer tanks makes it somewhat weaker on the mobile offensive and in sheer firepower, even with more IFVs and the Helo Inf battalion. It still has enough tanks to be offensive capable, just that a more traditional tank-heavy unit might have a 4-battalion regiment (3 tank, 1 Mech Inf) would have the advantage any open-terrain fight. The unit combines the best of Army and Marine Infantry-centered organizations.

Looks okay but you might think about adding organic air cav attack troop w/recon ships. Also some GSR, UAV, etc. By mid 21st you'll probably have a lot of robotics in your force, so some sort of tech support will be needed.
