I'd argue that it's completely unfeasible even in the face of trouble from the east.
Second, the critical positions. I don't agree that we need to take and hold them all, simply because we don't have the forces and time to do so. Taking them also involves moving into difficult terrain with short lines of sight, where the mostly infantry enemy forces have an advantage. I propose we instead clear the positions I marked yellow with fire and then keep them under overwatch, resorting to assault only if fire at range proves insufficient.
The positions marked orange I regard as "good to take, but not absolutely necessary", because they're quick to move in and out from.
