Where to find ASF and CSF ships to sale?

nowhere, you can't buy them

You can be part of ASF or CSF though, not relationed with clans or RP, as you can be within a clan and also be part of ASF or CSF.

Good question, must be some form of application for this!
We will inform u ASAP!

Yet, there are certain requirements for joining any of the sides, you can still apply, but start being a true ASF at an emergency or when passing the tests(and requirements).

As I was informed in game that I needed to be possably higher in rank, But looking on the forum I have searched and found only basic information about the ASF and CSF being hostil with one another, but no information about applications or level of char.

As I said I have done a search on the forum but found little information.

I have however done as was sujested and created a char for the side I want to be apart of and am waiting to speak with someone about more info in game.

About requirements, there are 2 main ones, having 100 hours online on this server, and to be accepted (and trusted for ASF side).

About hwo battles and events go, you can find good info at the "Contest Rules" at the rules list: http://www.crossfire.swat-portal.com/?project=rules
