reached rampant levels with the majority of the arms being smuggled from the United States.
As Mexico manufactured no weapons of its own, acquiring arms and ammunition were one of the main concerns of the various rebels, intent on armed revolution.
Under American law at the time, arms smugglers into Mexico could be prosecuted only if one was caught ''in flagrante delicto'' crossing the border as merely buying arms with the intention of gunrunning into Mexico was not a criminal offense.
Given the length and often rugged terrain of the American-Mexican border, the undermanned American border service simply could not stop the massive gunrunning into Mexico.

imposed an arms embargo on both sides of the Mexican civil war, and not until February 1914 was the embargo lifted on arms sales to the Constitutionalist rebels.
Despite the arms embargo, there was much gunrunning into Mexico, as one American official complained in 1913: "our border towns are practically their commissary and quartermaster depots".
Guns were smuggled into Mexico via barrels, coffins, and false bottoms of automobiles.
General Huerta avoided the American arms embargo by buying weapons from Germany.
