The friend of a fallen Green Beret set up a GoFundMe page, initially seeking $15,000 to help the family of Army Special Forces Staff Sgt. Mark De Alencar.

But in just two days, donations have flooded the page to the tune of $200,000-plus and counting. 

De Alencar, 37, was killed a week ago by small-arms fire in an operation against ISIS fighters in eastern Afghanistan. 

His death occurred in an area where the U.S. military dropped the so-called "mother of all bombs" Thursday on a terrorist tunnel network, killing 36 ISIS fighters.

The woman who set up the page, Nikki Damron, wrote that she and her husband were close with De Alencar and his wife. 

De Alencar, a Maryland resident, also leaves behind five children.

"Mark was recently killed in combat during his teams rotation in Afghanistan. He leaves behind a loving wife who now has the task of raising their 5 kids on her own. The youngest being 3 and the oldest being 17 if I recall correctly. This will be a very rough task on both his wife and the older of the kids who will be forced to take a larger role in supporting their younger siblings," she wrote.

The U.S. military said after the MOAB strike that it was not in "retaliation" for De Alencar's death.
