The "enemy lines" are rather vague and hazy, and more importantly they stay in contact with base.
Also, there's a reference to the film Cast Away, which didn't exist in 1995 (it was released in 2000).Anachronism Stew: The F/A-18F Super Hornet depicted in the first film didn't have its first flight until 1995, and then didn't enter service until 1999, making it unlikely to have flown during the Bosnian War of 1992-1995.Adrenaline Time: Used quite frequently.Actor Allusion: Burnett's superior officer Reigart is played by Gene Hackman, who had his own go with the Trapped Behind Enemy Lines scenario in Bat*21.He only directly engages an enemy at the very end, both because there's nowhere left for him to run while he awaits rescue and because said enemy, Sasha, was the same guy who executed Stackhouse. Being a lone navigator with only a sidearm for protection, he spends nearly his entire ordeal running for his life from the Serbian forces hunting him down. Action Survivor: Burnett in the original film.Dark Action Girl: She's actually Malen, the mysterious arms dealer that the CIA knows nothing about yet is still working with, and is playing the SEAL team for fools.Action Girl: Zoe in the fourth film, the first example of such in the series.
