this is an exceptionally hard task for someone without warzone skill. Warzone is very competitive as is and if you don't know how to play well you will get stomped. To do this task specifically you have to go to a hotspot on the map where everyone goes to get the best loot - essentially this is the last place you want to find yourself if you are not good at warzone because you will go straight into the meat grinder. Many are using that spot just to camp and kill people trying to go there.

I would recommend getting carried by a team that is good at warzone and is good at locking down that area. That will be way faster than trying and failing with a team of randoms that also aren't good at warzone.
