KABUL, Afghanistan (AP) — The U.S. military’s workhorse rifle — used in battle for the last 40 years — is proving less effective in Afghanistan against the Taliban’s more primitive but longer range weapons.
As a result, the U.S. is reevaluating the performance of its standard M-4 rifle and considering a switch to weapons that fire a larger round largely discarded in the 1960s.
The M-4 is an updated version of the M-16, which was designed for close quarters combat in Vietnam. It worked well in Iraq, where much of the fighting was in cities such as Baghdad, Ramadi and Fallujah.
