Hi all,
basically the sikh martial art revolves around fighting more than one person, (as sikhs were always outnumbered in battle)
gatka, is not considered the full martial art but part martial and part demonstration.
it will get one perfectly ready for the truely authentic art of the sikhs which is Shastar Vidya (science of weaponary)
the sikhs have a whole granth (bible/text) on warfare/strategy etc.
shastar vidya is alot more to the point (no pun intended) and unpretty, gatka is more common and commericial it is hard to find a shastar vidya practicioner.
Shastar vidya is mainly about ending a battle very quickly (not spending much time on each person) however gatka is very useful in preparation (flexibility, sword control, speed, stamina and hand eye co-ordination)
here is another more in depth video of gatka
