You can also disband alliances or kick members out if you wanted to. Alliances differ from Merc Corps because with Merc Corps, they are a unit fighting for the Inner Sphere while Alliances are made from members from different houses.
I would say the maxmium amount would be four because it is the equivalent of an Inner Sphere lance, while the minimum would be two. Lone Wolves could get in on the action too if they felt like it.
To add people you would have to click on their names, then you should see an option that says "Add to Alliance",click it and a box will appear and say, "Mr.Man want you to join his alliance,will you join?" as an example. Then you may either say "Yes" or "No". If the player say yes, then it will say the player has joined your alliance.
But while this is happening the host has to be patient because the player has to determine if he wants to join or not.
When in combat,the individual can bring their own mechs in the fight. Then once the game ends, the leader of the alliance shares the planet with the houses of the player faction if they win.
Their are many combinations for alliances like:
2 Davions and 2 Steiners
1 Marik and 1 Liao
1 Kurita, 1 Marik, 1 Davion and 1 Lone Wolf or
1 Kurita, 1 Steiner, and 1 Davion
If their is only two disadvantages to having an alliance, it is shooting other houses allied with you and allied planets being taken over by enemies whether it be another alliance or individual faction.
