Nobody thinks that having two infantry units in one commander is a very bad design? Maybe move the Pathfinders somewhere to another commander? And maybe add the Paratroopers to another commander?
The whole commander design does not really work. No one will do frontline drops with the team weapons because it is way too risky.
Having two infantry units is okay overall I would say. Some other commanders work like this as well. What I don't like it is that none of these units really replace another unit in your normal build.
Other factions do it better:
- Soviet Shock army: 120mm functionally replaces the normal mortar, Shock troops are bonus for flexibility
- Guard Motor: Same thing, just with Guards
- Defensive tactics: Basically completely replaces T2
- Lend lease: DshK replaces Maxim, Guards are bonus
- Osttruppen Doctrine: Osttruppen replace Grens, Artillery officer is bonus
- Mobile assault regiment: Two units replace stock units, third one is new
Plus, there is this intention with beacons to make them work together, but it is more of a gimmick than a proper feature.
Combine this with USFs fairly rigid infantry build order, and the fact that you'll get officer squads regardless if you want them or not, you'll overload yourself with infantry.
Neither Paths nor Paras are "classical" mainlines, they don't replace other units, you're supposed to get both of them, and you're supposed to still get Rifles and officers. It's just a bit too much.
