After listening to four very experienced SI's de-briefing Pl Comds orders, I detected some interesting 'Instructor Fads'. All four of them had a different SOP when it came to 'Actions on attack'. One said leave the model as it is, do not remove any cards or destroy it in any way. Another said leave the model untouched just pick up the cards. Another said destroy the model by everyone running across it on their way to their stand too positions. The final one said Pl Sgt destroys the model. I know we can't argue tactics, but 4 different DS on the same course with four different DS solutions, surely they could put their heads together and come up with a default answer, if only for the sake of the students.
