Example Input: [header] How to make absinthe cocktail [title] Mix a simple blend. [step] Add 3 parts ice-cold water to 1 part absinthe.

Example Input: [header] How to become a marksman (snipe) with a pistol [title] Choose a good pistol. [step] Though any pistol can be wielded better, the weapon can seriously limit the ultimate success of being a marksman with your pistol. Here are some generalities to look at when purchasing a weapon. <sep> (A) [substeps] King-the variable weapon of the pistol is the long barrel. It can deliver heavy rounds whenever you lay down to reload, or when you reverse the weapon, especially by pressing the " power " or " group " button. (B) [substeps] Stock up on ammunition for longbows (hence the name). This includes ammo including bbs, compared to clip types. (C) The generalities deal with single-shot, long-range accuracy; this is not including considerations like self defense, durability, or price. None of these are concrete as there are exceptions to all of them, and a pistol that fits you personally is always the best choice. (D) [substeps] A lower recoil is less dangerous on a pistol. Some shooters like a lmg pistol have a previously increased recoil to increase recoil.
