bk1 for heavy work like shelter building and clearing jungle and a bk17 for finer tasks like game cleaning and fire building. at least a tarp, a poncho, a jungle hammock, firesteel and water filter (probably a katadyn). a gi cooking set too. rifle wise i have to agree with saturatedshadow on this one a go with a 45/70 marlin lever action (i'm thinking guide gun with a magazine tube extension)
