Zardoz asked how he could spawn his own custom group for use in SOG AI. This is how:
1. When mission starts choose action "Wait for AI units to join player before SOG AI is initialized".
2. Press Escape to access debug console.
3. Paste 2 lines of code into console and execute them. The first line will spawn your desired group. Example:
grp1 = [getpos player, WEST, ["B_G_Soldier_A_F", "B_G_Soldier_F", "B_G_Soldier_AR_F", "B_G_Soldier_LAT_F"]] call BIS_fnc_spawnGroup;
(units grp1) joinSilent player;
