Now that you have the L1 Card, you can revisit the ground floor to access one of the locked rooms to the west. In this room is where you can get the Cardboard Box/A and x3 Chaff Grenades.

Next, go down from the mezzanine level and head east to unlock the other room. There is a soldier patrolling in this room, but he will face the wall most of the time. Near him is the SOCOM Suppressor that you will need. You can just sneak near the guard and grab the suppressor and then leave; taking down this guard without having the suppressor yet will be challenging as you will most likely sound an alert.
