Here are my two cents for this doctrine.
1a. I would like to combine riflemen flares and forward observers since they are largely alike
1b. Alternatively, I would like it to see forward oberservers to extended other units such as officers, rear echelons, and HMGs.
2a. I have experimented around in turning the IR pathfinders into a 2 man marksmen like the soviets but still call in arty barrages. Cost would still be 2cp and now 400 manpower. A lot people liked this
2b. The Barrages could be the Major Barrage but shared a global cool down. Not very strong but much more spam-able.
3. The Greyhound main gun needs to be buffed from 60 damage to 80 damage. Maybe additionally the armored skirts should already be upgraded as well. As suggested above, I would not like to see it to lay mines since it would be too overlapping with Lieutenant Tech because the Greyhound is an alternative to the Stuart. The M20 could use a bit of a rework like early WBP. (Weaker gun but cheaper to lay mines and support flanks.)
I would still like to see the standard Paratroopers over the Airborne Assault Group or Pershing
