Are there any Gruppe Sechs peds/outfits I could use for my FiveM server?
For the multiplayer ped, you can use EUP (requires patreon subscription)
Emergency Uniform Pack|Client/Server Sided|Easy Install|UPDATE 5.0 Announcement - FiveM Resource Development & Modding / Releases - Cfx.re Community
For peds:
there is: s_m_m_security_01
If you are subscribed as a Patreon to FiveM, you should use the EUP. My next update will include ALOT of new security divisions outfits.
Do you have Gruppe 6 peds in it?
