The two man team that was deployed to go do surveillance of the place Madam Crown was being held almost got caught, but they were saved by the arrival of a truck of men, about 24 of them.
So they were getting reinforcements, that means the kidnappers were not leaving any thing to chance. They were battle ready, its just unfortunate that they messed with the wrong family.
Even if the kidnappers brought 100 men more, they wouldn't be able to defect their team. When the area was safe, the team of two made their way back to their group.
As soon as the two men rejoined their team,and the information gathered was understood, the rescue team moved out.
The rescue team inserted themselves into the area. Some quitely used fast roping and claimed the roof while others stayed on the ground waiting for the order to attack.
