Stingers Mission Guide (Gold Medal) – GTA 5

Mission Synopsis
A message from Lester will state that he’s located a van equipped with stingers that will be useful for the next heist they are planning.

You will have to head to the back side of the police station Lester has mentioned. Jump over the wall and from there you will see the van that you are looking for.

There will be one police officer on guard. He will be too distracted on the phone and can easily be stealthily taken out. The mission will be way harder if you leave him conscious.
Taking it stealthily like this is an easy way to grab the Gold Medal for this mission.

Afterwards, you can grab the van without alerting the police. You will then have to deliver it to the delivery spot underneath the Olympic Freeway. Walk away from the vehicle and the mission will end.
