Everyone hate it because the instructors are all jerks and are
basically there to torture you instead of teaching. I took
TaeKwonDoe when I was younger and my instructor then was tough but
didn't act like a jerk.
Unarmed combat teaches you stuff but it's useless. Everyone who's
taken martial arts before knows that you need more than the 4-5
weeks of lessons to be efficient to use those moves.
My suggestion to the SAF is to have the servicemen take TKD
throughout their 2 years. Make sure that they at least ORD with a
Green belt. At least, one lesson a week. Put some of that tax money
into good use. At least, give the servicemen something that they
can actually use when they ORD.
Those who have their black belt will be assistant instructors when
the lessons are conducted. This way they can cut down on the number
of instructors and they won't waste the time of the black belt by
making them take lessons they'll get nothing out of. Plus if they
know the people, they will teach instead of torturing them.
