Joseph and Nuts aren't as good with their ranged weapons as the two hunters who use them professionally, but they do have them.
Leon drags everyone into a group meeting where they go over the planned route, what maps they have of it, how they're going to map and mark their progress- Nuts has a clever arrangement with surveyor's tools and known landmarks and math- And what everyone should pack, and practicing common trail hand signs (the important ones are 'stop', 'go', 'caution', and 'attack'), and what to do if they're separated (fire your flare gun, fresh from the machine shop, straight into the air, wait for eight hours, if no flare responds try to go back to the last major landmark the expedition visited), and so on and so on. They'll be moving with rope tied to each other if the weather gets bad and on dangerous slopes, but it's been good recently and there's no signs that's about to change.
