Fire Axe - for fire wood collection as well as wood based structures for shelter and defense. Also it is a decent weapon that takes relatively little skill to effectively wield.
German Shepard - loyal and lethal companionship, living thinking alarm bell, will instinctively assist in protection/attacking, could be trained to track game. Will gladly accept food scraps, the bones and flesh of my enemies, and pets as payment for services rendered.
Body armor - reduces risk of infection through scratches to body as well as mild protection against various weapons. Also an added insulative thermal layer for the cold. Body plate can be replaced with old thinkpads as needed
