This enforcer has only a handful of guards so just sneak inside and kill them. Use your intel view to locate the hostiles. There’s one sentry and the target is inside his room so unless you spook them, it’s easy to catch them off guard with a well-placed grenade. You can also get a good vantage point in the stairs, if you want to eliminate him silently.

He leads the porno shooting portion of this racket and you can find them in an auto-service shop. Sneak in from the back and take out his men covertly or deliberately make some noise so when they go to check up on your, you can just lob a grenade to kill the target and many of his men immediately. Before leaving, don’t forget to loot the cash stacks and bag, as well as destroying the boxes of reels and films as marked in your intel view.

There are a lot of people but he only has a handful of guys and a sentry. He'll be sitting inside of a the second floor room so you can't really snipe him. If you want to kill him covertly, you can deliberately lure his men one by one to your ambushes or go loud and take them out. Be careful since he has a powerful rifle that can take a good chunk of your armor and health away. Once cleared, collect the money stacks and bag to keep them for yourself.
