You did not specify which body armor the targets were wearing. We already have body armor that stops multiple .338 Lapua rounds and considering that Arma3 is set in the near future is not unlikely that soldiers will be wearing better armor.

This is not a bug, silencers increase bullet speed and range.

But you can shoot trough the window of a strider, so not the whole car is bulletproof.

Is someone still going to look into this?
