the aruk first wave was 6000 strong , the artillery , tanks , mines and others knocked out around 2000 or so , this left 4000 charging across only a few miles of land , the speed of the aruk in full charge was impressive , it could move only like an animal very fluid and abrupt , the mass of flesh was a target rich environment , but with reloads time measured around 5 times a minute the aruk were able to cover the distance and quickly enter the outer trenches .
