un-group the pack (if they're placed too close, they'll group up by default - then just press F2 and drag off the grpLine from each d00d.)
Then make WP's for each moron, and set their behaviour to either SAFE or CARELESS - the latter if you don't want them to hit the dirt when they see an unfriendly soldier.
You can make them CYCLE by putting a "cycle" type of waypoint as the last foreach unit, preferrebly put upon (or close to) his start pos.
And set the SPEED in each WP to "Limited" to make 'em walk calmed.
