Let us assume human trafficking, since that's a thing SpFarce would normally bust on their own. Plus, that makes sense with the contact being some kind of pimp and he doesn't want his business undermined by some new business.

I'm thinking a small-to-medium scale operation, a shipping container full of dames to be rescued, with the security being semi-beefy. 2, maybe 3 armed guards patrolling the container of girls with 4 taking perimeter around the place, maybe a few guards just roaming around with no specific patrol route. They likely don't carry fully-auto SMGs, but they would probably carry around shotguns since those are a lot easier to come by. If anything two of the four perimeter guards are carrying SMGs. Most everyone else is carrying a pistol in addition to the shotgun if anything else. Cover is fairly easy to come by if we assume this is a standard warehouse gig stationed near a strip mall, as warehouses typically contain a large amount of crates and things to hide behind.

Anything else that I should likely address? You're the de-facto leader of LF so I was going to follow what you were going off of.
