O.C. GROUPS

1. Owing to the scanty information at present available it is impossible to fix definitely the limits of front and tasks to be allotted to each Group.
2. It may be assumed that if the limits of the front remain the same as those mentioned by me at a recent conference with Group Comd^rs, the zones will be approximately as follows:-

RIGHT G^p      A.8.b.45.55 to A.2.d.74.75 (Eastern Boundary)

A.8.a.20.33. to A.2.c.61.59 (Western Boundary)

CENTRE G^p    A.8.20.33. to A.2.c.61.59. (Eastern Boundary)

A.7.b.28.45. to A.1.b.73.23 (Western Boundary)

LEFT G^p         A.7.b.28.45. to A.1.b.73.25 (Eastern Boundary)

F.12.a.15.15 to F.6.a.54.10 (Western Boundary)

1. If the front is extended as far East as A.9.a.55.50 then as follows:-

A.9.a.55.50. then as follows:-

RIGHT G^p A9.a.55.78 to A.3.c.58.46. (Eastern Boundary)

CENTRE G^p thence to Western boundary as in para 2.

LEFT G^p no change
