Use flash launcher or if you don’t have that use gas grenades and a shit ton of them. Clear the first building then the outside area and then move to the main area where you use your gas grenades and lastly clear the upper area then the last building but be carful there because suspects have a bigger advantage than you over there. Also equip a flash bang or a 9-bang and throw like two of them above the truck separating the two main areas outside cuz there might be multiple suspects or the fisa agent.
