But what i was referring is, during the time troops are doing
crowd control other Units are mobilised in defensive positions
around Beijing's perimeter should other area's unit come in to take
over Beijing.
Oh, I get it now. I remember reading that some tank BN had
deployed with their turrets aiming outwards of Beijing, & the
foreign press took that to mean they're defending against outside
units entering their turf. But there was also supposedly a rumor
that they only had blank rounds or something.
Hard to say, lah. The "Tiananmen Papers" book also revealed one BDE
commander famously refused to obey orders to suppress the students
(he was arrested, briefly jailed & disgraced), so I assume the
disagreeing factions might have been enpowered only up to that COC
level then.
Transferred to local context: Can, say, 1 SIB (or 54 SAB or a PDF
BDE) fire on a "mutinous" 7 SIB? That's a clearer scenario, isn't
it.
No, still no idea what I'll do. Other than perhaps with 7 SIB, I
don't think the SAF has emphasized significant identity building at
that command level. Instead, the focus has been more at the Unit or
DIV level. As far as those two extremes go, a rebelling unit will
be quickly & easily surpassed, while a division is too big for
any insurgent army IMO.
