I've a friend in field defence squadron, the RPs of Air base. I
think the training for both sea soldiers and FDS will be the same.
Basicially it's like a Adv Infantry training. Learn to dig a lot of
stuffs, trench, fire trench a lot of digging. You'll learn plt and
section live firing. I think maybe fibua with plt and section
movement. It's a tough course.
But after pop from course, just do guard duty till ord and shift
work cuz no one in navy will do guard duty, only you guys. Then
depending on your PC, you'll have turnouts. But since it's navy, it
might be different.
