IRAMs in Iraq
The Washington Post reports a form of improvised rocket propelled munition being used against US troops in Iraq. According to the report:
U.S. military officials call the devices Improvised Rocket Assisted Munitions, or IRAMs. They are propane tanks packed with hundreds of pounds of explosives and powered by 107mm rockets. They are often fired by remote control from the backs of trucks, sometimes in close succession. Rocket-propelled bombs have killed at least 21 people, including at least three U.S. soldiers, this year
The report notes that these weapons are generally used at closer range that other RPGs and create large explosions. The report also highlights the widespread use of propane tanks as a basis for explosive weapons in Colombia.
