On the 10th Jan 108 Fd Bty moved into the first FSB YS4577 position close to, or at FSB Alanbrooke. No survey was required as the Bty was covering the movement of 1ATF up Route 2. They remained in this position for 4 hrs only.
A 2nd FSB, a harbour for the night, was established at YS 4583 in the Xa Bang outpost area.
131 SURVEY

Early on the 11th the Taskforce including 108 Fd Bty and 161 Fd Bty was airlifted into FSB Berryman. Late in the afternoon, radar was airlifted to the FSB while B Bty 2/35 Arty also moved into FSB Berryman.
131 SURVEY
As the location was in tall timber, theatre grid from known points could not be accessed. The 3 Btys,( 108, 161 and the 2/35) were placed on Regimental Grid along with the Radar.

22. On 10 Jan Op Duntroon commenced. There were three FSBs involved during the operation, two of which required svy. FSB A at YS4577, did not require survey, was only occupied for four hours. At FSB B YS 4583, Regt grid was provided for the two batteries occupying the area. In the third FSB, BERRYMAN at YS3986, the three Btys involved, 108, 161 and B 2/35 plus the deployed radar were put on Regt grid. The original plan was to provide theatre grid, but the FSB was a relatively small clearing surrounded by high trees which made higher survey impossible. The svyrs again deployed as an LP, as C/S 31G which is now becoming well known on the Div Loc net.
