Thanks for the bugreport, I will fix that.
The Panzerfasut was removed to keep the okw version inline with vanilla.The Wehrmacht version lost its smoke grenade. That way both units have the same amount of abilities while not being identical.

The intention of the werhmacht unit is to make the lategame more intresting. Most earlygame squads have less potential in lategame compared to units from other factions. Instead of buffing them, I added two new units in tier 3 to fulfill that role. Gebirgsjägers for long range and stationary usage. And Fallschirmjägers for assault and close-long range (depending on the upgrades).

I see. It makes sense given that Ostheer does seem to lack late-game elite infantry designed for rapid offense. Though it's rather jarring considering how rarified the use of Fallschirms are. OKW Fallschirms are already behind in terms of usage, more so with how late and inconvenient the Ostheer variant is.

As I do not own all the commanders in the faction, did you happen to replace any command abilities in the Luftwaffe doctrines that will grant you call-in Fallschirms? Because being able to only access them via Tier 3 and the support officer seems to hinder their deployment onto the battlefield.

From a functional standpoint, it's certainly an interesting dynamic to see them used as assault troops and given the process of Ost's tactics, they're definitely a welcome addition compared to OKW that needs infiltration specialists due to their limited army.

The issue I have with them is how they basically replace Brandenburgers/Stormtroopers. While they won't have access to Tactical Advance to substantially increase their anti-infantry capacity; their more accurate and fully-automatic FG42s as well as costing the exact same amount of manpower (at 340) seems to make BBs rather redundant at that point. The MP40s pale in comparison to what the Fallschirms get then. While I do understand that BBs can be accessed earlier in the game, it just feels like Ostheer has a lot more important things to spend on like a Half-Track or Opel Med Truck whereas in the late-game, they can afford to send in Fallschirms for a change in tactics.

Additionally, me and my boyfriend were having an interesting conversation about this and we found it very amusing because the function/role of the units are completely reversed from their historical counterparts which only added to our severe confusion of their combat roles.

Fallschirms early in the war were used just like the Oberkommando variant, to infiltrate enemy lines and neutralize hardpoints, cutting off the enemy to make way for the main army groups' offensive.
Whereas later in the war, Fallschirms were used primarily as elite supporting infantry much like the Ostheer variant does.

It was quite funny how their design philosophies are the exact opposite of their real-life versions. I'm not saying that changes need to be made as gameplay-wise, they fulfill the necessary roles, it's just amusing!
