US vs Iran
Similarly, for mountainous regions or cities, Jeeps equipped with RAAD-T. Tosan or Toophan TOWs are much more mobile and effective (not to mention cheaper) than Infantry Fighting Vehicles (IFVs) or tanks. Their anti- armour missiles could be launched from 3 to 4 km from their target.
In 2005 Iranian Television reported that Iran has begun to produce heavy machine-guns with armour-piercing bullets. Iranian Defence Minister Ali Shamkhani said the 12.7- millimeter gun has a range of 2.5 kilometres and is suitable for snipers. 
Recently Iran began manufacturing armour piercing bullets for AK-47s. Currently the Iranian forces are being issued with these new bullets to counter American body armour. Iran claims that these new bullets could penetrate 20mm of protective vests’ armour.  These bullets are sure to increase American casualties in any future conflict with Iran. You can imagine what the casualty rates would be if insurgents in Iraq or Afghanistan get hold of these guns or bullets.
Other favourite weapons of the IRCG are the Fajr-3 and Fajr-5. The 240-millimeter Fajr-3 missile has a range of some 25 miles. Production of the Fajr-3 missile, with an estimated range of 45 km, was estimated to have started in 1991. The Fajr-5 missile, which is launched from a mobile platform, reportedly has a range of between 60-70 kilometres. Like the Katyusha rocket and the Scud missile, however, at the limit of its range it is accurate only within a radius of around one kilometre. The Fadjr-5 rocket launcher system has a primary mission of attacking ground targets. However, with the installation of a radar system, it also may have the ability to track and attack seaborne targets. There are unconfirmed though plausible reports that Iran has tested a chemical warhead for the Fajr-5.
