I think one of the important factors that a unit won the best
combat is motivation. The best unit competition takes in
IPPT, range, standby, ATEC, IRL inspections etc. 1 SIR
& 3 SIR won the best combat unit in the
late 1990s as both units have very good COs who can pull & push
their guys the right way. As a result, the main factor that their
men fought for their lives is for their CO.
I have an NS mate serving in the former 3 SIR best unit now 596 SIR. He
served as a driver but he got IPPT gold all
the way during NSF. He told us that time they
work like hell not because of SAF, Singapore
or friends but for their CO. They do not want to let Sukh Singh
down.
