subscribers using message characteristics unique to MR was These messages were subsequently observed on the watch group originated by an unidentified group serving the DMZ Front on terminal which was 27 November.

One message, also unique to units of MR3 north, was sent by this same unidentified terminal to the DMZ Front on 27 November.

Other technical characteristics displayed by the group serving the probable 32fth Division possibly indicate that this unit will or is presently serving infantry regiments in the Laotian panhandle for unknown points south.

The deploying subordinates of the 32@th Division probably include two suspect infantry regiments, an artillery regiment, and an unidentified regimental-echelon subordinate.

SIGINT indicates that the other two subordinates of the unidentified regimental-division, another suspect infantry regiment, and the possible 14th AAA Battalion of the Headquarters are unlocated. All deploying subordinates and the 32/th Division will remain in MR3 north.

In summary, the SIGINT through 30 November indicates that at least eight subordinates of suspect artillery regiments, two of suspect infantry regiments, and three unidentified regimental-echelon subordinates. Evidence suggests the 32fth Division is heading for points in South Vietnam.

As noted, its deployment may possibly be through the Laotian panhandle or passing through the DMZ area. The 32fth Division's destination is unknown; its deployment may possibly be through the Laotian panhandle or to points in South Vietnam.
