Hello, Can a prone model declare move, cancelling prone (and gain LoF to another model), and then finish moving in prone again?... in other words stand up, shoot and end prone Thanks
No, you can only change stance (enter/exit prone state) at the start of your move, guts, dodge or any other movement, and then you finish in that state. You need another move to change again.
Small anectdote - you can change your Prone State once per Movement Skill declared, not just once per Order. So you can declare Move-Move stand up in the first Short Skill and go back to Prone in the second Short Skill. Just have to declare multiple movement Skills in the same Order. No Attacks, pretty much. Discover doesn't work either because it doesn't have the Movement Label.
