My guess is one officer visited the US (or watched a movie) and
saw US soldiers in Grey Pt shirts. And being the impressionable
young fella that he is, his mind has forever associated the grey t
short with fit, strong professional soldiers. And so he gets on
with his life until years later, our hero, now a grizzled old man
suffering from arthritis and all sorts of other ailments, he finds
himself in a position to decide what color SAF soldiers should wear
when exercising. And those memories from his sweet sweet youth came
flooding back (brining a tear to his eye) and the rest is
history.
Just a theory though.
