Errors of position means that one party set out a fire but accidentally hit one’s own. Such incidents are deteriorated by close proximity of combatants and relatively happen more frequent during the First and Second World Wars. At that time, wars usually in a deadly mess based on troops fighting in close combat and there is no accurate target. As weapon was made more sophisticated, this class of incident becomes less and less but still occurs once a while. The most significant recent representatives happening not long ago were in Afghanistan during operation enduring freedom. The case caused heavy casualties by laser-guided bomb mistakenly called in on friendly forces. Larger and higher expectation is this giving away to current target and less damage.
