Hello,
Try the following:
bob switchmove "FXStandSur"
For "FXStandSur" you could also try the following moves:
FXStandSurDead
FXStandSurDown (Stand and put hands behind your head)
FXStandSurUniv (Hands behind your head surrendering)
put these into a trigger or work em into a script
Hope this helps
ps: you should really check the Unofficial Operation Flashpoint Command Reference Manual, and look under character animations.
