Thinking about buying it for PS5

Thinking about buying reformer for the ps5. Came from PC playing Arma 3 for many many years. PC got burnt so now I game on the ps5. Does anyone know what the player limit is per server? Also, squad size? Am I able to invite friends over to the server I join? Do teams scramble after every game? Are the game modes available on the ps5 player vs ai only or are there player vs player modes? Thanks in advance for any answers i get!
