Answer 1

Good answers here but here is another that is true even today. In many of the wars, a significant percentage of deaths were from friendly fire. I have seen number for WW2 that maybe 14% of allied deaths were from friendly fire. The numbers even today are high, although I don’t know if they are the same as WW2. So sometimes you don’t know who you are shooting, bombing whatever, and it ends up being your own side. It happens a lot.
