"The United States recently sent Lebanon 72 M198 155mm howitzers and 25 million rounds of ammunition (mostly for rifles, but also thousands of mortar and 155mm shells). The U.S. valued the shipment at $25 million but that was being generous. The Americans began replacing their 1980s vintage M198s with M777s in 2007. Thus the United States has lots of M198s that were going to be scrapped or put in storage (and eventually scrapped). Artillery is much less in demand since the 1990s because of the development of cheaper and more accurate guided rockets and artillery shells. That said, the Lebanese were grateful for the American howitzers since these are still useful and Lebanon received them as a gift. " (thanks Marc)
