Generalizations in pencak silat technique are very difficult; styles and movements are as diverse as the Indonesian archipelago itself. Individual disciplines can be offensive, defensive, or somewhere in between. They may focus on strikes (pukulan), kicks (tendangan), locks (kuncian), weapons (senjata), grabs, or even on spiritual development rather than physical fighting techniques. Most styles specialize in one or two of these, but still make use of them all to some degree.
