Diplomatic Siege (also known as Enemy of My Enemy) is a 1999 American production filmed in Romania. In the United States embassy in Bucharest, Romania, Steve Mitchell (Peter Weller) and Erica Long (Daryl Hannah) are pressed to disarm a nuclear bomb left over from the Cold War that's in countdown mode. Serbian terrorists take over the embassy and threaten to kill one hostage every hour if the US does not release their colonel being held for trial at the Hague for war crimes. Meanwhile at the Hague a disgruntled Croatian guard kills the Serbian colonel for massacring his family, so US has to find an impersonator to fool the terrorists in negotiations. Gen. Buck Swain (Tom Berenger) arrives in Bucharest with a US anti-terrorist squad to retake the embassy. And there's a mole on the embassy staff.
The following weapons were used in the film Diplomatic Siege:
CIA agents and some terrorists in the film use M1911A1 pistols.
A bodyguard is armed with what appears to be a SIG-Sauer P228 pistol, judging by its trigger guard. It could also be an early model P229, which was introduced a few years before this film was made. However, the pistol is obviously an airsoft replica, because real SIG P228/P229s are compact designs with short slides and barrels that fit flush with the muzzle. This pistol was previously misidentified as the similar-looking Zastava CZ99, but the distinctive SIG hammer and thick trigger make this impossible.
Smith & Wesson Model 629
Members of the US Special Forces in the film are seen using MP40 submachine guns. Since the film was produced in Bosnia-Herzegovina, the SMG was most likely the closest to a western-looking firearm that the armorers could find that actually could be fired (the M16's seen earlier were replicas).
PM md. 65
Several characters in movie use early model PM md. 65 assault rifles with underfolding stocks and convex forward grips.
PM md. 80
Some members of the Romanian police special unit carry PM md. 80 carbines with 20 round magazines.
M16 Rifle (MGC Replica)
Mossberg 590 Cruiser
F1 hand grenade
Serbian uses a F1 hand grenade.
SPG-9 Recoilless Rifle
A SPG-9 recoilless rifle is mounted on an Automecanica Moreni PM 7 armoured vehicle used by the Romanian police.
Serbian terrorist Petra (Irina Movila) fires an RPG-7 at the gates of the US embassy.
