I'm with Marshall on this one. Assuming that the boss also told that previous team that it was a heist and hiding the real objective, it's a serious waste of time and resources to lie about it. State the mission, get to the point, and hell, a billionaire can easily afford $50 million anyway (assuming honor system here). Creating diversions to isolate the queen didn't seem to be a problem -- two people on their own did it just fine, and the zombies weren't all that concerned with the bank heist anyway thanks to the trade of the rapey guard. Hell, the mission to get the queen without hiding the body is what led to the downfall of the mercs, but more people means more ways to dispose the body and not attract the zombie king.
Moreso, when the boss gets the call that the mission is proceeding as planned, he nods to two high ranking military personnel about it. Either the boss is working with the military or those two top brass are in on the scheme and are working with him on an unsanctioned mission, either way the boss has way more resources than a ragtag team of a handful of mercs.
And lastly, the boss's plan relies on too many variables, the two biggest ones being whether his one, single mole can outwit nearly a dozen other mercs, and whether or not one of those mercs can actually repair the escape copter.
Then again, it should be noted that this mission is what causes the worldwide outbreak ultimately, so no, there aren't really any strategic geniuses at work here. The zombies were already contained and the nuke would have done its job, but because of the mission, Vanerhofe was bitten, escaped, and will spread it to Mexico City.
And whoever decided to drop paratroopers onto a zombie horde really deserves a dishonorable discharge.
Haha WTF was the actual plan there?!? Just drop some guys into a ravenous zombie horde and hope for the best?
