Recon Support is almost certainly the weakest commander of the US forces.
I wrote a guide for it and I like it but like you said the Airborne Company far more robust and reliable.
The biggest issues:
- Forward Observers, the Riflemen Sight Boost Passive, is just not appreciable. Stand still in cover and note how much your vision range increases. It's like... 35 vision to 40? ~15%? Not impressive.
- Recon Sweep is something you can get from the Major for free. The Major's call-in plane has less vision but it is cheaper.
- The Greyhound is arguably worse than the M20 and always arrives later than an aggressive M20. The M20 is just a really good unit. The Greyhound is fine but tends to arrive late.
- The Airborne Combat group is trash like you said. Expensive. Unreliable. Pure manpower sink in an army that suffers for manpower.
It suffers.
The strengths are the I&R Pathfinders and the Greyhound in the right circumstances.
Hopefully it will see some boosts in due time.
