# Foxsch :
Am I in the wrong thread?
Correct, all ACE questions belong in the ACE thread
(when we refer to ACE we mean ACE2 as we are in the ArmA 2 / Operation Arrowhead forum). You need to use self interaction and interaction keys to place satchel charges etc. And iirc ctrl + f to switch to grenades. F is only used as a fire selector in ACE2.
