Sit and STAY!

[Black Fox]

I feel like an absolute noob, but for some reason this isn't working for me. I've got a group of Russian soldiers sitting around a fire, and I want them to react when I start shooting at them.
Two things are going wrong- first, they won't stay sitting even before they spot me, and second, they aren't reacting when I open fire.

I am using effectstandsitdown and setbehaviour safe. Where am I going wrong?

(FYI it's worked for me before, I don't know why it isn't working now.)

ARe the russians in a group? If so they wont stay down. ALso if they don't have weapons they wont stay down either.

They have weapons. OK, I'll try ungrouping them. Then I'll synch them individually to the "Resistance-detected" trigger that is in place nearby.
Thanks for the info.
Incidentally, do you know WHY it doesn't work in groups? Just a foible in the game design?
