In the game the MP40 and Luger both have 9mm cartridge, witch is supersonic and gives a supersonic crack or bang when firing.
The Thompson and Colt use .45 APC cartridge witch is subsonic and dont have that loud crack. They only have the noise from expanding propellant and the weapon action.
The problem is that Thompson and Luger(somewhat) have soft sound, without the loud crack
And the Mp40 and Colt have the loud crack or bang.
(this kind of error was in mohaa too)
“wishlist”
Wouldn’t it be nice if the covert ops would get a high-damage bolt-action unscoped but (extremely)silenced weapon that would do 100 damage to the chest and about 150 to the head? Instead of the FG42 (atleast at the close range, the damage could decrease a bit on the distance)
Im thinking about De Lisle silenced carbine. It would be a cool tool for executing the enemy with it. The slow reload on bolt action would balance it out. (maybe even having to the alt-fire button to rechamber another round, exactly when you choose to, wich would be really cool)

It is one of the most silenced weapons ever made.
You could only hear the firing pin strike and the action of the bolt when recharging another round.
