BZ Gas Grenades Mission in GTA 5

BZ Gas Grenades is a mission in GTA V given to Michael De Santa by Lester Crest if the player chooses the Smart Approach for the Jewel Store Job heist. This is the second setup mission for the smart approach of the main heist.

This mission starts after delivering the bugstars van to Lester. In this mission, Lester gives Michael the route of the Humane van that has the gas grenades required for the heist. Michael has to intercept the van on its route to trigger the setup mission. The player can kill the guards and hijack the Humane Labs Boxville, however this will give the player a 3-star wanted level.

The better option is to shoot open the back doors of the van causing the cargo to fall out from the back. This also rewards the player with the gold medal for the mission. After collecting the cargo in this way, the player will receive a 1-star wanted level which they have to lose before delivering the grenades to the garment factory.
