Recon:
0CP: Forward Observers
1CP: M1 81mm Mortar Team
240MP, four men, same stats as the Soviet PM-41. White Phosphorous barrage at Vet 1.
4CP: Recon Sweep
5CP: M8 Greyhound
Comes with armored skirts, gun from the Stuart, pintle MG from the M20. Slightly increased armor and health. Increased cost to 280/50 and population to 8.
8CP: 155mm Artillery Barrage
This is the same that is normally available on IR Pathfinders and in Mechanized Company.
I still disagree with some points, but I also cannot deny that this form is far superior to the original. The airborne gimmicks are taken out, and replaced with some generalist, practical abilities.
Both AI issues and preview patch eliminates the mortar team though, maybe bring back IR Pathfinders, where their unique flavour is they can spawn from ambient buildings? They can have a version of beacons that not only lets airborne stuff drop in tighter radius but has much larger sight range to serve a recon role; this commander no longer has any paradrops so that's meant to compensate. The IR Pathfinders retain their 155mm call in, but its cooldown can be global and linked with the off-map one so you cannot spam the ability.
Some more ideas on revamping IR Pathfinders: they can call in paradrop for 1x BAR + Bazookas for 50% increased cost (ie 150 munitions instead of running back to base and saving 50), would serve as good support role for regular units.
Greyhound performed too powerful and therefore a bit too similar to Stuart. Maybe instead of coming with pintle, it can be an upgrade where you choose to have an observer to call down something (like decoy barrage or T-70's observer toggle or even a "Forward Capture" toggle that allows taking sectors without having to debark the crew), or the classic MG. Similar to how Elite Armoured Doctrine's Panzer Commander works.
Another simpler idea is to just let M20s upgrade to Greyhound variant for a small munitions cost, everything else stays as-is.
Mechanized:
0CP: Assault Engineers
Cost increased to 300. Now has five men. Damage on Grease Guns decreased from 4 to 3,2.
1CP: Dodge WC51
MG has the same stats as on the M20. Slightly increased armor and HP. Population increased from 5 to 6.
2CP: Withdraw and Refit
4CP: Recon Sweep
10CP: M4A3(76)W Sherman Command Tank
Costs 380/150. Has the same stats as a normal M4A3, but has +20 sight range, can't change ammo and has a larger gun with better armor penetration. All nearby allied vehicles have their accuracy increased by 20%. Can call in a targeted P-47 rocket strafe.
I still prefer if it has M3 with Assault Engineers, and the first call-in are Cav Riflemen, plus halftrack gets that repair ability that was from the AA campaign; that might forego the need for Assault Engineers from a repair perspective. Some mods have that featured. I also think this should retain the 155mm off-map.
Anyhow the ideas are not my personal favorites, but I have to say they are still better than the originals.
