No need to be afraid of military service.
For that matter, no need to try to beat the system wholescale
either, at the risk of backfiring.
There's a variety of service vocations available if you don't get
combat-graded. But imagine kena condemned status, & end up with
an actual appointment that adds an added dimension (loneliness) to
an already-subservient vocation - eg. storeman in a way-ulu base
who must wait for soldiers to drive in at 5 am or 2 am to
draw/return ammo respectively.
Also, some prospective civilian employers may view your PES
classification prejudicedly down the line, regardless of how you
attempt to clarify your actual fitness.
I understand MO's are now less unsympathetic about lowering medical
grades than before anyway.
