I wondered about this also. I have often heard that Ireland is archaeologically underexcavated/reported and that there are big important sites and backlogs of transcribed literature etc. which have yet to be excavated/reported/translated etc. but I never heard of anything like these cycles before.

The "tank" unit is cool too, I remember the description said something about a partially-intact suit of such armour being found somewhere, any info about that?
