I thought as a non 3CB member I would offer a bit feedback from my perspective.
Firstly though, a bit of background. I don't have a military background, unless you count digitally. I was a beta tester for Panther Games Command Ops and I've played mainly Steel Beasts and
Falcon 4 (BMS), Harpoon (now Command: Modern Air Naval Operations) and that's about it. What I like is realism, so when I got into Arma 3, very recently, and when missions and campaigns lost their appeal (too scripted and far from realistic) I found 3CB (I think via YouTube and MeFirst). I've played a few times on the public server (PS), when commitments allow, and though it's certainly fun and something that engages me, it does tend to get a little "playful", especially later on. Oh yes, commitment, unfortunately this has stopped me from fully registering with the unit, though I would really love to one day. For example, I rarely get home, from work before 7:30 pm which pretty much negates the recruitment training. When I saw the announcement for the public server events, I was thrilled. My wife is much more social than I, and something on a Saturday night, if not every week, was indeed, a regular possibility.
Any way back to the feedback.
I initially was (self) assigned 1-1-C: Rifleman AT (NLAW) - happy with that, as I'd got a couple of good BTR/BMP (I know they are different Arf

) kills earlier that afternoon. So after a quick pic (I think) we went to embus. After a couple of minutes and after a few FFSs, we were ordered back to the FOB respawn area. And I'm glad we did; Jetrise gave us ALL a brief; which is something that is missing from the general PS, where it's shall we? could we? why not? It was a great intro into the operation and very immersive...thanks.
When we went out, we had almost immediate contact, but I noticed that I had no sound effects (not good). so I thought it best to restart Arma (hoping I would get the same slot). BTW, sorry to who ever I asked to shoot me in the head to get me out of the fight: his reaction was classic - I didn't realise there was recriminations for that - again immersive realism

. I didn't last long! "CONTACT, WHERE? I CAN'T HEAR...". When I restarted "my" slot was filled and the only
real option was 3-1-D: Fire Team Leader [1-Delta] - I KNOW!! I didn't play as FTL, obviously, but it did give me a great insight into the comms.
When I got to the unit, we progressed steadily, mainly giving overwatch support to other section.s Although this was potentially slow paced, orders are orders and we stuck to it under the leadership of Cpl Bunny. At one point, the whole of Fire Team Charlie and two of Delta were killed by an IDE - a bit too much mirth for full realism, but f**k me, it was funny. BUT HANG ON, I'm now SC! After requesting tasking from 1-0 for a 2 man Section (plus the possible ripsaws, sorry reinforcements), I quickly handed the reigns (the long range) over to Mne Havok (I felt a bit ashamed of that, but felt it was the right thing to do in the situation).
The operation kind of finished soon after that, where did that 3 hours go? So, Jetrise, not boring at all. I did stick around and after lurking and eves dropping with some 3CB grown ups (I felt like a naughty boy in the teachers common room

) it was decided we spend 40 mins tidying up the remaining tankers. Riding in [real] low on the running boards [sic] with Jetrise piloting was a REAL thrill (I think I actually squealed like a girl!).
So to summarise (I only came to say TANX). F*cking ace evening; a nice bunch of members, regulars and newbies. Please keep the public events coming, like I said I can't attend every week, but I will give the wife a fiver to go to the cinema whenever I can afford it.
TANX
