1. Place a player unit.
2. Place a random number of units (Preferably 10 or more) of the same side as the player (No need to group them).
3. Preview the mission, and execute the following piece of code in the debug console:
{ if (!isPlayer _x && side _x == side player) then { _x joinAs [group player, 30 + (floor random 200)] }; } forEach allUnits;
4. Try to command some of the higher numbered units. You have to scroll through several empty pages to get to them.
