Hahaha! Yeah, i do face the same problem but only at the undertaker undergound hideout. Took me 5 mins plus to "lure" him out from his hiding spot.
Anyway, more funny moments to share. Those jeep patrol is another fun thing to kill. Last night in my gameplay, i roll into one of them so i jump off my precious Jeep Wrangler to avoid it being shot and i hide behind this big tree and maneuver according to the charging jeep patrol.
The gunner got off the jeep flanking from the right so i killed him and left the driver. He was reversing and ramming onto the tree until the jeep explodes

I laugh non-stop while looking how stupid he is.
Another jeep related joke, I was scouting this new outpost and accidentally shot my sniper rifle. So the militias go scattering around to find and while some jump into the jeep. Thanks to the driver of the jeep, he reversed, killed 2 mate hiding behind the jeep while killing another one who was looking for cover while accelerating. Only left is him, the jeep gunner and a sniper uphill

But my theory goes here, i realized that some militias have certain attitude. Those with vest die trying while those half naked with bandolier seem to be abit timid and love to hide till the all clear confirmation by their mate. If you listen to their conversation during on alert the best speech for me is this :
"its only one, i can do it, i can do it. Go out and kill that mf, GO GO GO"
