Editing GURPS (section)

===Combat===
Like most other RPGs, combat in GURPS is organized in rounds. A turn is equal to one second of real time. In one second, a player can make her character take an action, such as attack or move. Free actions are simple actions that can be done at any time. Characters in a party have a set initiative every round that is based upon their Speed.

There are two kinds of attacks: Melee (possibly with hand-to-hand weapons) and Ranged (e.g. bows and guns). Attacks made by a character are checked against their skill with the particular weapon they carry. For instance, if a character is attacking with a pistol, it is beneficial to have a high level in the Firearms skill. Like any other skill check, a player must roll equal to or less than the level of the skill to succeed. Failure means a miss, success scores a hit. Similarly, rolls of 3 or 4 are "critical hits", which means the weapon deals its maximal damage to the target. Attack modifiers are set by the GM when factoring in things like body armor and cover.
