how do I change probability for a group?

[arthur666 10]

Where and what text do I use to change the prob. of appearance of a whole group? I want a 4 man patrol to maybe or maybe not be in a mission.

Set the squad leader's probability at whatever % you want with the slider bar (half way = 50%), then name him: s1. Now, in the 'Condition of Presence' line for each of his squad members type:

alive s1

Now, if the squad leader spawns in (50/50 chance) the rest of his squad will do the same...
