Overlap? Since when did obers have camo and ambush bonus?
They took away Faust but made the unit field earlier, so you could argue they diversified it more. Obers don't come that early so you can fit a couple of squads in your build quite easily.
Also AT capability just doesn't fit the role of falls, they were notorious historically for being caught unprepared when something as simple as a Bren carrier turned up in Crete for example. Suffering heavy losses.
Actually I would like to use this post to bring attention to the battle of Crete, which was a batshit crazy operation that succeeded against all odds.
When the paratroopers landed on Crete, they were hopelessly outnumbered and outgunned. The reinforcements got cut off or shot down, and most of them were unarmed, due to the guns being lost(which of course didn't stop the Australians and British from shooting them, warcrime alert). The German style of leadership,with everyone of every rank involved on the frontline fighting, quickly incurred some heavy losses on the German division command. Additionally, the British knew about the operation beforehand due to intelligence, and have been practicing fighting against airborne assaults for months, shifting quite a big number of troops to Crete and fortifying, entrenching and preparing the island for months beforehand.
So what happened when that unarmed and outnumbered Fallschirm division landed in the midst of a hugely superior enemy force, locked in with them on an island?
They ripped the defenses apart. They didn't even have any anti-tank weaponry, and still destroyed all British tanks, including the Matilda tanks.
Endresult: 23000 allied losses, recoverable or unrecoverable, to 5000 axis ones.
Crete was an absolute unicorn and hollywood movie of a military operation. It's the real life equivalent of Connor McGregor beating prime Mike Tyson. And they then did it AGAIN in 1944.
Oh and I'd like to add that the standard K98 SmKh round penetrated 18mm RHA and was fully capable of penetrating a Bren carrier from the front.
