The body of the fourth U.S. soldier who vanished along with three others last week in Lithuania was recovered Tuesday, the Army announced, bringing to a close an exhaustive search following the sinking of a 70-ton M88A2 Hercules recovery vehicle into a quagmire of mud and water.

The Army has not released the names of the soldiers pending notification of the next of kin. The bodies of the other three soldiers were recovered Monday.

The four, all members of the 1st Armored Brigade Combat Team, 3rd Infantry Division, based at Fort Stewart, Georgia, had been participating in a relatively routine training exercise near Pabradė, a Lithuanian city close to the border of Belarus -- a staunch Russian ally. The unit deployed there in January as part of the Pentagon's bolstering of NATO's front lines amid Russian President Vladimir Putin's invasion of Ukraine.

"This past week has been devastating. Today, our hearts bear the weight of an unbearable pain with the loss of our final Dogface Soldier," Maj. Gen. Christopher Norrie, 3rd Infantry Division commanding general, said in a statement. "Though we have received some closure, the world is darker without them."
