Marauders

Have you ever gone for a nice stroll along the road anywhere in the Wasteland? No? Didn't think so, see these here are the Marauders, and their favorite game to play is "fuck the wasteland with mines", though mostly in the south. In order to win, a Marauder must plant as many explosives as they can, everywhere they can. Currently the Establishment line has prevented much of this bomb fetishism spreading to the north.
Marauder Suiciders have the admirable penchant to burn themselves on fire and run toward target to explode in flame. Killing them has 50-50 chance of themselves will explode on death. Marauder Diggers can throw mine spear which explode when near. Torchers can throw molotov cocktails which explode with a wide blast zone. Shooting that bottle too near would get you doused in fire. Side note: burning pieces of Suiciders is one reason for heavy graphical demand in OP.
The leader of a major concentration of Marauders is a priest figure, with one fixed location being the 1st floor of Bison Steve Hotel. He cant be target in VATS, and killing them (in real time) can get you poisoned. If you dont clear up most of his minions to prevent distraction first before engagement, he can kill you any time.
Marauder Bomber Rat, despite being hostile toward humans, still can be considered an animal member of this group. Like Suiciders, they will approach targets and explode. Despite being a weaker member of this group, its explosions can kill such as Legendary Cazadors.
Main reason for Bomber rat inclusion being Psykers can use its corpses to summons, same way as with other Marauder corpses.
