Monocycles

I'm in the army. My squadrons task is to herd sheep every day. We do this for a bit, then suddenly one day we come out and there is another group of sheep at the end. Immediately i start moving down the side to get a head start to herd them back, but my squadron commander blows his whistle and everybody sits down and all the sheep turn into kids. One of the kids raises his hand and asks "Does anybody ever try to invade your fort?". For the first time I notice a fort off to the left of us. Our leader says "Yes, but we have to shoot them". Suddenly, I flash To a scene of somebody running towards the fort and being shot down. I view that scene like it was in a movie, with the perspective being on the ground and to the left. Suddenly I'm back to the field. The same kid raises his hands and asks "How old are they?". "usually about 70-75, guess they just can't resist the treasure" says my squadron leader.
