There are two linesmen in soccer whose job to officiate the game. Each linesman is assigned on each half end of the playing field. As what their name suggests, they are patrolling the length of touchlines between halfway line as well as the goal line. They are carrying flags that are bright in color as a signal whenever the ball left the pitch as a result of the following:
- Corner kick
- Goal kick or
- Throw-in
Linesmen will be waving their flags at the same time in order to get the attention of the referee if they believe that they’ve seen a foul.

Lastly, it is the responsibility and job of a linesman to signal when the attacking player is in offside position by means of raising their flag. To be able to have the best view of the game and make such call, the linesmen stays level with the team’s last defender at all times.
