Officers are trained to accept painful orders and ensure
that it is carried out (without question and without hesitation).
That is drummed into them during OCS and for the first two years of
service or when they reach captain. Because an officer is only as
good as his ability to receive and give orders.
It seems you know much about the training of officers and how
they are "taught" to react. Do share with the NCOs and enlistees on
the insight you might have.
What drives the men are the NCOs. The backbone of the
armed forces. Ask any scout, pioneer or commando. Seldom do these
elements operate as a platoon (the smallest size where you'd expect to see
an officer). There basic leadership is practiced hands on,
from the ground up.
It seems you have not heard of LRRP teams and BRC teams? The
officers become Team-leaders of at least 3 other men. Would that
not be smaller in size than a platoon, or even a section?
