As of 11am 13th April, after game update, the leaders on Nords will no longer intercept, if the changes on the change log go ahead. As a result you will need to either kill all 3 camps up by the final leader or block one of them. Gone 1am here so not working out a block - others can play with that maybe. I have simmed all 3 camps up top for minimum losses:
Right hand camp: 150Karl
MMA 220XB = Zero losses
VET 250XB = Zero loss
MG 100R/170XB = Zero loss
Middle camp: 150 Housecarl
MMA 94B/126XB Lose 65 to 94 Bow, Ave 81Bow
VET 67R/1E/182XB Lose 53-67R, Ave 61R
MG 55R/1E/214XB Lose 42-55R, Ave 50R
Left hand camp: 150 Valkyrie
MMA 220C No loss
VET 250C No loss
MG 270C No loss
You might then want to sim the leader as it may well be possible to lose less militia on it by suiciding
