A free kick in rugby union is usually awarded to a team for a technical offence committed by the opposing side.
Free kicks are awarded for technical offences such as playing too many players in a line-out or time wasting at a scrum.
A free kick is also awarded for making a mark.
Once awarded a free kick the team must decide how they wish to play it.
Furthermore, the defending team can attempt to charge the kick as long as they have first retreated 10m.
