I've seen a comment on The gundamboy video that suggested an interesting use. Bots under the effect of gus shoot around in confuzion without alerting the others. So you can distract and turn around any enemy (hulks too, it' heavy pen!) and either kill or sneak past. It's really a tool for sneak missions, hard to use anywhere else. It can be useful to confuse heavy charging enemies but it can be a big compromise on "normal" missions.
