If at all possible, find higher ground that is difficult to reach by zombies, and easy to defend for you. Always find an avenue of escape before engaging in combat, for all combat in reality can have deadly outcomes.
Always abide by local laws and law enforcement when acquiring or practicing with weapons. In such a scenario and in all survival scenarios, all weapons require skill and proficiency to be used effectively, whether combating zombies or ‘bad guys’. That said, all weapons are dangerous and deadly, and should be practiced with professional supervision. This post discusses about an unlikely but a possible scenario of a zombie infested apocalypse, and all suggestions should be taken with a grain of salt. Disclaimer: The use of weapons below may be considered rather gruesome and graphic, and is not suitable for children under 13.
