@gavvet,
"A calibration error on artillery pieces led to the shelling of own troops and subsequently significant delays."
You reminds me our last war against terrorism. Time mis-calculation is a terrible error and it can't be fixed! Eventually it ends by killing our own brothers by our hands :/
Great article and thank you very much for sharing it with us! 3 Attacks on 3 bases at the same time, that would be a great war tactic!
Cheers~
