Actually, most guard units aren't given the time to work on serious PM on a weekend. We were lucky if we got any time during the annual training. Mission completion is the goal. If I've got troops coming in to camp for the weekend at 1AM, up at 5 for hauling troopies to the range on an all day rotation, out to the range for final pickup after midnight, then a 6 hour drive home on Sunday, I'm not going to put them on wirebrush and touch up paint. I want them safe drivers. The basic daily PM, oil, tranny, lights, fuel, tires, by the book. Rest and food for the rest of the time. The rest of it can wait until the maintenance shop says it needs a repaint.
Yeah, if the hinges squeak, we hit em with oil for "noise discipline"
'course, i also was not a good motivational leader and could not convince these guys to take the initiative if they did have the time. The platoon sergeant before me rented a big screen tv in the back of the M105 up against the back door of the GP medium.
