Last year I submitted a 3 tier SOCOM divisional reformation structure here . But since we're numerically much bigger than SOCOM and are unable to hold JSOC I worked on a newer one recently .
First take out 3 para sf battalions.
Namely : 9 para SF ( Operational History and Publicity)
10 Para ( Operational History and Eqts)
And any other one of choice
And use them as the base for next gen SOF adaptability
Train them in Their respective fields of warfare . Since Urban Environments are becoming more and more in common and modern hence every division has to do Urban Combat training in their respective regions
9 Batt - High Altitude, Arctic/Snow , Mountain and Hillforest and mountain Urban Combat warfare (Northern division)
10 Batt - Desert , Dry Hill , arid-Semi arid regional (western to North Western division)
Any other batt- Hill Forest , tropical, urban,jungle and swamp warfare
And then just compose a small SF unit . Grow up eventually. For equipment baseline, use 10 since they have the best standardisation of comparatively morr advanced gear.
Also throw out the rest of the Tavors back to exclusive Parachute Regiment utility and bring in all the m4 carbines and go for a new rifle based on that .
