Hi, Good memories Jacob. I can remember putting a bag or two of those plastic soldiers to use down on my grandpa's farm years and year, AND years ago myself.
Used to build 'dug outs,'  'bunkers,' 'mg'  nests and such in the side of a creek bank down in a gorge and then getting off a hundred yards or so on the other side, up on a hill and shooting down into them and trying to hit something (anything really).  It was there that I found out that bullets do not travel in a straight line from the barrel to the target. Ha, ha! Back in the good old days. Thankfully the cows were over on the other side of the other hill.
Take care, Sgirty
