Wrong. RSM is not No 2 man in the unit during wartime. Chain of
command shall be follow during wartime, CO, S3, Support Coy OC,
Riffle Coy OCs, PCs than RSM, CSMs, PL sgt.(S1, S4 & QM are not
in as they will not be in the main body most of the time) RSM will
not know the battle plan as much as the office as his duty is to
maintain the unit discipline & organize task to respective NCO
to ensure the unit is function.
