The U.S. and South Korea are scheduled to kick off a scaled back version of its annual springtime military drill starting Monday, Seoul said, as both countries remain in the grip of the coronavirus pandemic.

The joint drill — the first under U.S. President Joe Biden — will run for nine days and will be a “computer-simulated command post exercise,” South Korea’s Joint Chiefs of Staff said in a statement.

The “defensive” exercise will not include outdoor drills or maneuvers, which the JCS said have been held throughout the year, while the number of troops participating will also be “minimized” due to the pandemic.
