Back in 'Nam

Intro (I've been having some wicked dreams y'all and just as my bio says I shall make these dreams come to fruition,this is some made up battle in Vietnam or something idk I just need a setting) You get a radio in from your commander,all soldiers from your battalion are to be sent to the frontlines asap,so you grab your M16 and hop on a helicopter to frontlines,after a while you feel at peace,tranquil,relaxed...until a SAM rocket hits the helicopter and you crash,a few minutes later you wake up,everyone else is either dead or ran off and you're M16 is lost,you only got your bowie knife now,as you try to stand up you realize that there's a metal rod jammed into your leg and taking it out is risking more blood loss,you also realize that you cant see out your left eye...but at least you can fashion together a makeshift eye-patch,but still be weary of Vietcong traps,ambushes,patrols and snipers
