Blowing up Armories and Supplies
If you interrogate guards, some will tell you there is an armory or a small building nearby with food. You may have recognized these places because the armories have different ammo refills and you may have found food packets. Blow the building up with TNT, and that guards in the surrounding area(s) will complain of starvation, making them easier to knock out, and they always mutter "I'm Hungry" giving you clues about their location.
