How do you change a group's formation?

You can change the formation type on the fly using the scripting command setFormation. Values should be one of the following:
  • "Column"
  • "Stag column"
  • "Wedge"
  • "Ech left"
  • "Ech right"
  • "Vee"
  • "Line"

In ArmA a couple of additional formations were added.

  • "FILE"
  • "DIAMOND"
