After keeping 3 crates in your vehicle, drive it to a lockup or garage. Third crate, with which you can now complete your task, is kept on the first floor. Again, on right hand side, when you enter, there is a room and second crate is kept inside there. If the noise bar becomes full then officer(Colonel Fuhrberger) will wake up and if this happens two times then army officer will call police and you will fail this mission. The moment you enter, you can find 1st crate kept on right hand side corner. At time of burglary, keep track of your noise level with help of a noise-bar shown on your screen. While stealing crates, Ryder will wait outside the house for you to keep a watch. Then you have to steal minimum 3 crates full with guns out of total 6 crates. Once you start it, after a small cut scene, you have to drive along with Ryder to a army officer's (Colonel Fuhrberger) house. It can only be played between time 12:00 and 20:00.

I've discussed in depth details of the challenge below.
