First off do not. These men are extremely skilled and have some of the best quality armor and weapons in the entire game. 3 of them could easily take on 10 of us if we are not prepared to the fullest for everything they can throw at us.
Their communication is impeccable, their tactics flawless, and their gear of the best quality.

Organize, outnumber, out gear, and out tactic are all requaired to even consider fighting them.

If your gear is not q 95+ do not even consider it.

If you do not have 4 for ever 1 of them do not even attempt it.

If you do not have the unit formation skill dont even try.

too many people are dead and dying because they underestimated our enemy. However every single faction currently hunts them down. So work togther, and we WILL win this war.
