Ok guys - no I DONT EXACTLY request the sounds of that simulation^^ I know there would be copy right issues:P Also they still can be improved in terms of qualitiy.
But besides that - Steel Beasts is a great example for massive and powerful tank sounds.
You can feel that since the tanks feel powerfull and massive even if the grapic representation is pretty basic. (apart from the interior modelling)
Arma 3 with sounds like these would stun;)
- Just giving some inspiration here;)
Best regards!
