yes, support arms go for common phase in astw for 2 weeks. I
went for the 5th Common Phase and the total strength was about 90,
with engineers, Armour, Arty, Guards, Infantry being there. i don't
think cdo goes to sispec.
in common phase you'll have a day of tbtl, which is team building
team learning, and how to conduct it etc.. and you'll learn alot of
leadership stuff, and also about ammo control, about informal
punishment, blablabla. No OPS. I think its weird that you know that
you are going for common phase but yet don't know that sbo/ chiong
sua equipment is not needed. they do give out store list when you
go for briefing..
And NO you do not get your 2SG rank after the course. I've got 1SGs
in my course who attended even the ops phase. then what? promote
them to SSG? not really applicable yeah? besides, you're only
attending 2weeks of common phase and want to get 2SG?
rumor has it that you get the 2SG rank after you have served as a
3SG for a year, and has attended PS course.
