The United States has delivered more than $25 million worth of military aid to the Lebanese Army, Reuters reported Sunday night, to help it "defeat the terrorist and extremist threat from Syria." 

"We are fighting the same enemy, so our support for you has been swift and continuous,"  US ambassador to Beirut, David Hale, stated at an event. 

The announcement came amid a flurry of statements from US officials over successes in the international coalition against Islamic State (ISIS) and other rebel groups, and Washington has been working closely with Middle Eastern powers to combat the threat. 

But it also surfaces amid multiple instances of US-made weapons appearing in the wrong hands - the rebels' side. 

In April 2014, a "moderate" Syrian rebel group was spotted for the first time firing a US-made antitank missile - raising some concerns over how the weaponry could be used and whether arming Syrian rebels would become a US foreign policy point

It is unclear whether the weaponry was supplied by Washington or by a US ally such as Saudi Arabia, possibly with American approval.

Two months later, ISIS in Iraq seized a host of US Army equipment, including several military aircraft

Even civilian equipment has been found to have been seized by the rebel group: in December, a Texas resident received death threats after ISIS uploaded footage of his truck being used as an anti-aircraft battery. The truck's owner, a plumber, stated that he had no idea how the truck had made its way to Syria.
