 FACT: When Sarge and Destroyer confront and kill a monkey hiding in  a section of AC conduit in front of them, they fire their weapons  from approximately a 50 degree angle (i.e. if the floor is "6PM"  then the ducting is at about "10PM). However, when the targeted  ducting is shown, the bullet holes are perfectly parallel to the  floor. Something that could have only happened had they shot from  directly the beneath the air duct.
