The PR community is a mixture of PUB Players and semi-organised clans and some very organised heading towards mil-sim clans!!
You will get a very good idea as to the nature of the game and the community by playing a few rounds on
various servers.
With regards to clans, I can only comment on my own and other experiences that I have had;
We fit into the 'semi-organised' bracket. We have an active PR player count of around 25 and
with this we are able to scrim against other clans in 'friendly' events every few weeks.
For these events we carry out planning and deployment training, and then look to fill any gaps
in player knowledge at these times. Just by playing alongside a clan like ours you should get
a very quick all round general knowledge of the game. BUT, I really would not join a clan until
you get a feel for how you would fit within it. And whether or not the game is actually for you.
The community is on the whole very friendly, despite how some of the posts sound. There are
some particularly bespoke mechanics to PR that give it a teamwork bias. So I would advise
you at least skim the manual before you ask questions about what most of us now take for granted.
You will get the response you need to advance in PR, however it does take a little respect
from new players towards all the hard work that the DEVS as well as the community have put in
over the past 5 years or so.
"If I'm curt with you it's because time is a factor. I think fast, I talk fast and I need you guys to act fast if you wanna get out of this. So, pretty please... with sugar on top. Read the Faffing Manual!"
