Advantages
- Save squad space
As recon squads only take 2 people, and CAS has 2-4.
- Instant communication
the recon squad can provide valuable intel or tell the CAS to prepare for laze.
- Priority
because of the fast com. recon squads can be given higher priority and this can be especially useful to the team since recon squads often seek HPTs (enemy armor, FOBs, major offensives). Also the CAS can know what they're targeting and decide if a bomb/missile is worth it. Often times, CAS gets wasted on trivial targets like half a squad of grunts (especially on public servers
The only disadvantage i can think of is sorting out who's who when creating the squad (since multiple people wanting to do the same task (like spotter) might join), and possibly overflowing VOIP (mumble mumble mumble ppl)
