Depends on whether you in PTP stage or fit/fat squad.
after PTP stage, you're either in BRT or Fight Fighter or
ERS.
after BRT, you will either go into SRB, Clerk, Store, Instructor,
Medic.. etc.
in BRT, you learn basic casualty transportation, learn some rescue
equipment, learn how to use fire extinguisher. and you'll be
preparing for foot drill competition. Bravo company seldom win,
always Alpha. Charlie got win some though. LOL.
Oh, also got the route march.
for ERS, I posted in the other post, I'll just repeat it
here:
there will be a few major milestones to overcome.
Presentation Skill - just presenting any topic u
want for 20 mins. I taught the class how to play a guitar.
Footdrill Commands - how to give basic footdrill
commands. turn left, turn right, turn back, turn front, U-turn,
march here, march there..
IPPT - minimum Silver (I so proud to have attained
it, because I never passed IPPT b4) 
SOC - A pass of completing it in 09:30 mins.
BAPT - Doing some gym exercises (pulling weights,
brisk walking, cycling at a certain speed, and endless ladder)
while wearing the full fire fighting gear , and the BA set (got
time limit to wear everything, or else fail). then going through a
rat maze filled with traps in the darkness and smoke, to find your
way out before your air tank whistle blow (which means u left 10
mins of air). So even if you're totally tired, you have to force
yourself to control your breathing, so you won't consume too much
air.
Final Exercise - You have to take on the role of
either first Sect Comm, Intelligence(I forgot the proper term for
it) or DO, and use whatever you learn to lead your 40 fire fighters
to fight fires in different scenarios. There's oil tank fire (need
alot of brain power and planning, calculate wind direction etc),
ship fire fighting, 2 room fire, 3 room fire, underground rescue
mission, ktv fire, flashover, Chemical Agent incidents, Mass
casualty, Suicide, Flashover.
the skills you'll pick up are:
how to carry 3 lengths of hoses, how to lay hoses, how to recover
hoses, how to operate hydrants, how to set up BA, how to use the
hose sling, how to operate rescue equipments, how to transport
casualties, CPR, how to bandage wounds, how to use medical
equipments, how to set up ladders, how to operate the pump and
primer, and other vehicles, impulse gun., long layon, rappelling.
etc.
Basic Task Manual (BTM): various drills, you'll hear S1W3 alot.
How to tackle Flashover fire (the most exciting experience), the
fire is 1000 degrees.
Very exciting I tell you. 
We will dance where the devil lives...
Fire fighters go through the same thing, but they train for 3 mths,
while ERS train for 6 mths.
I don't know about medics though, I know they got learn infusion
and stuff, cpr, ambulance stuff.
