Iraqi Security Forces is ready to fire at known ISIS locations near the Iraqi-Syrian border using an M109A6 Paladin Self-Propelled Howitzer, June 5, 2018.
About a mile from the Iraqi-Syrian border is a US military fire base where approximately 150 Marines and soldiers are still hammering ISIS in Syria with artillery.
"To get to the firebase, you fly by helicopter over Mosul," NPR's Jane Arraf reported on Monday.
"And then just a little more than a mile from the Syrian border, there's a collection of tents and armored vehicles in the desert," Arraf said, adding that the US troops have been at the remote, temporary base for about a month.
In early June, the US Army released a dozen photos showing the base and the troops firing M777 howitzers and M109 Paladins to support the Syrian Democratic Forces clearing ISIS from the Euphrates River Valley.
Then a few weeks later, the Army released photos of the troops playing an improvised game of baseball as dusk sets in and smoke clouds billow in the background.
