To participate in NATO's Very High Readiness Joint Task Force (VJTF) drills in Poland, Germany had to scrape much of its arms and equipment "from all around the Bundeswehr," Bartels said.
That's why Germany should significantly increase its military spending, Bartels argued.
"Dramatic changes in the field of security require drastic changes," Bartels said, according to Die Welt.
To completely equip the army, Germany needs to significantly increase its defense budget. NATO requires all its members to spend 2 percent of their GDP for military purposes, but Germany spent only 1.16 percent in 2015 and 1.15 percent in 2016, the Bundestag member said.
