There is a Platoon Recruitment section for each platform where clans/platoons post to recruit new members. They usually provide more specifics in their recruitment post.
I recommend checking those sections out and see what each clan/platoon is about and see if you come across one that may interest you.
Some clans ask for subs but very few.
If you look at the top of each platform forum page you will see a link to the clan section of the forums.
Some are small and some are large with different agendas towards playing the game.
Not all will suit you but most are friendly and will welcome you getting in touch.
The main benefit of being in a clan is developing a group of like minded friends who you can regularly play against.
Well worth a look. Back in my PC gaming days I was in a clan called Essex Rifles. We had our own forums and organised our own group nights on battlefield, playing on our own servers. Occasionally we’d set up clans battles with other clans.
Great bunch of people too.
Want a competeive one? Make one
Want a casual one? Make one
Want a server based one? Make one
Want a Forum field one? Make one
Are you a Youtuber or Twitch Streamer who wants fans to come together? Make one
Want a military simulation? make one
Want one for tank users? Make one
Want one for pilots? Make one
It’s for anyone for any purpose you make it out to be or want to join.
Yeah a mic is preferred though not always necessary as the idea of being in a clan is to communicate, socialize and enjoy squad play irrespective of whether it’s competitive or not.
Having been a part of squadrons and clans in the past my personal advice would be to avoid trying to start your own.
It can be time consuming as there’s more work involved than people realise.
Your best bet is to shop around and try some clans out to get a feel for it first.
Worst that can happen is you might make some extra friends while you’re at it.
