Baker insists his fellow squad members follow him to an incoming helicopter. The incoming ""VIP"" turns out to be Baker's twin brother, who brings along a skate board that the whole squad uses for fun. Carl Baker turns out to be nothing like his brother: he is hard-drinking, womanizing, party-goer. The two brothers end up in a fight, nearly destroying the base in the process. Carl celebrates their birthdays by bringing in a truck-load full of Vietnamese hookers. They all party down and, in the end, Baker ends up doubly-mad as his brother ""steals"" his girl. Carl leaves the next morning with neither brother on speaking terms and everyone in trouble. Carl's helicopter goes down and Baker goes in after him, managing to get caught by the same VC who have his brother. They are both tortured by the VC and Anderson and Goldman must go in to rescue the two.
