Sergent Maximus

After Nam, PTSD hit him hard, so he turned to the bottle.  This cost him his home.
One day he was contacted by three ghosts, the ghost of wars past (a civil war veteran), the ghost of wars present (a Nam vet, like him), and the ghost of war future (a cyborg with a laser gun from the year 2014).  They told him that he must build an army to fight the evil PTSD monsters that attack soldiers everywhere.  Thus, Sergent Maximus was born.
He carries a rubber band powered paperclip gun, an airsoft gun that jams every few shots, a shiv made from a tooth brush, and a med kit, consisting of whatever he could find on the dead or stoned people he comes across.
He is most often seen at his recruitment booth, a tarp-building in the vacant lot behind the VFD.  He also raises money to by Dr. Jack Daniel's Miracle Elixir, mostly by collecting scrap metal to sell at the scrap yard, though occasionally he asks nice people on the streets to help his cause.
