The VA does have significant information regarding Agent Orange use in Korea along the demilitarized zone (DMZ). DoD has confirmed that Agent Orange was used from April 1968 through July 1969 along the DMZ. The military defoliated the fields of fire between the front-line defensive positions and the south-barrier fence.

The size of the treated area was a strip of land 151 miles long and up to 350 yards wide from the fence to north of the "civilian control line." There are no records that reflect spraying within the DMZ itself.

Agent Orange and other herbicides were applied through hand spraying and by hand distribution of pelletized herbicides. Although restrictions limited the potential for spray drift, run-off, and crop damage, records indicate that effects of spraying were sometimes observed as far as 200 meters down wind.

Units in the area during the period of use of herbicide include:

the four combat brigades of the 2nd Infantry Division (1-38 Infantry, 2-38 Infantry, 1-23 Infantry, 2-23 Infantry, 3-23 Infantry, 3-32 Infantry, 109th Infantry, 209th Infantry, 1-72 Armor, 2-72 Armor, 4-7th Cavalry); and 3rd Brigade of the 7th. Infantry Division (1-17th Infantry, 2-17th Infantry, 1-73 Armor, 2-10th Cavalry). Field Artillery, Signal, and Engineer troops were supplied as support personnel as required. The estimated total number of exposed personnel is 12,056.

For purposes of claims for service connection, if a veteran is determined to have been exposed to Agent Orange in Korea or in other recognized areas (e.g., Panama), then the presumption of service connection for the listed diseases applies.
