It's an M16, a reliable, widely adopted military firearm, so ammunition is plentiful. Furthermore, 5.56x45 is a pretty compact round, so you can carry plenty ammunition. It's accurate, and has low recoil, making it a pleasure to shoot. Only problem with this rifle is that it is prone to jam when shit gets into the bolt, due to the gas piston operating system. So maintaining and cleaning this weapon is must. Which might not make it an ideal primary if your going through mud and shit.
My first choice in this category would really have to be a 10/22 ruger. It's quite, incredibly accurate, and easy to maintain. And I can carry a couple of thousand rounds on me no problem.

That looks like a Heckler & kock USP. Another very reliable firearm. Comes in 2 variants, the 40 and the 9. Hope this is the 9 variant that uses 9x19 Parabellum. An accurate, quite, and compact round. Plus this comes with a silencer to boot for situations when stealth is called upon.
Would really prefer a glock in 9mm with an attachable silencer. Glocks are AKs of the pistol world and you can bury one for 2 years, dig it up, shake out the dirt, and immediately fire a couple thousand rounds through it without fail.

Can't go wrong with a bat. Knives can rust, chip, and grow dull. Especially katanas which are traditionally made out of high carbon steel such as 1095.
Would prefer a crowbar though. A wider range of applications. Going from caving your skull in to prying open a door.

Because it's fucking rope that's why. You know how much shit I can do with rope that I can't do with binoculars, a flashlight or a fucking swiss army knife?

It's a tank.
