think those are different lah...those generals and
colonels...
like they signed up as regular for 1st one or two contracts, like
for 6-9 years, which they obtained till LTC etc...then subsequently
never continued contract due to better jobs prospects found
etc...so they ORDed...
then when they do reservists, they maintain the rank of LTC and
after 3-5 ICTs may get promoted to COL before they RODed...
think of those specialists which signed on till 1SG or SSG, then
think ARMY no prospects or never promote them so they go for other
jobs, when they come back for ICT, they may get SSG (NS) or
2WO(NS)...
etc.
