The platoon is challenged to plant a dummy bomb in the Officer-in-Charge's office located inside a secure compound, which is protected by a guarded bridge. After exhaustive suggestion taking from the others, they decide that they need a scheme to cross both the bridge and get into the compound; Walker then says that he has something in a warehouse near the compound that can help, and explains his plan: they disguise themselves as firemen as it would allow them to enter the office to plant the dummy bomb. To assist in this plan, they get a 'secret agent' to travel to the compound and start a fire in some wooden crates that would be left near the compound in advance.
