This might be me misunderstanding what the command does but I didn’t find clarification on the comms manual and it has pretty odd behavior anyways.
If you order your wingman, element or flight to chainsaw via keybind they will stop using missiles and go guns only for the rest of the 3D session no matter what command I issue after. If I use “Go grinder” from the element context menu instead they will perform the tactic and behave normally.
My guess is the “chainsaw” command from keybind does something completely different(command to use guns only?) but since the dialogue on both commands say “(package) go chainsaw” I assumed maybe that was the way to keybind the grinder command.
This is very easy to replicate and I can provide acmi as well if needed.
