confusing description

just notice the marder II description which suggested it to be support by the Stug and is unlikely because both will not available in the same upgrade.

Is it just misuse of text or the tech tree is wrong anyone can clarify?

It's you not the text :P.

Don't know where you read that because clearly the text says otherwise:

QuoteSummary: The Panzer Support pool has available the Marder II for use as an effective tank destroyer to combat Soviet armour. Armed with the 7.5cm PaK 40 and armour piercing rounds the Marder II - while more vulnerable than the fully in-cased StuG III - is highly capable at silencing Soviet advances.

The Marder II is able to target enemy tracks; immobilising them - allowing for easy take down by localised tank fire or small infantry assault. Be aware the Marder is a fragile unit and should attack from maximum range, supported by Panzer IIIs.

Eastern Front's Marder II uses a soviet divisional gun F22 re-chambered to use german PaK 40 ammunition.

'In-cased' should be 'encased', but other than that the English is fine.

Maybe you've read Panzer IIIs as StuG IIIs?

oh, indeed, forgive me then, my fault.
