To add completion to this, decimation was a Roman Legion punishment that was really high up in terms of severity. The Centuria was a roman military unit of 100 men (The centuria size/meaning actually varied over time) but when the decimation punishment was applied that would mean that (by draw) every 10th men in the centuria would be killed, here is the catch, the people of their own centuria had to kill their own mates in decimation.
