I think the people here are simply interested in the subject and
as a result learn about it however and wherever they can. It's a
hobby. It's fun! Of course, many of the people here have served NS
and seen at least a bit of military life. Some people are really
"pros" -- like Viper52 who is really in the aeronautical industry.
But the main thing is interest.
Don't count on the US coming to save us if we get in trouble. Very
bad assumption to make, since the US has no foreign policy, merely
foreign interests. After all, the unofficial SAF motto for office
holders is ENSURE, DON'T ASSUME! 
Along with ENDURE AND EXCEL for the men, cos
the office holders are going to make their lives hard.
