I think there are no rules prefix. It arrives an agreement with the opponents.
Rules that I use frequently:
-Limit size 0 units (too annoying, if there are too much)
-Limit artillery (like 5-10% of total pts.)
Less common:
-Ban all cluster and bomblet ammunition (too powerful)
-Ban rocket launcher artillery (too powerful)
Never:
-Limit infanfry to something like, 4-5 companies. (No need to limit in desert maps)
-Get some pts limit that you _have to_ put on tanks / MBT's. (something like 30% of total pts or something. The game is named winspMBT after all.)
-If you have gunships / air strikes, you have to tell beforehand that you have them, not what you have or how many. (Frustrating to buy sam's when opponent does not have any targets for them.)
-You can only capture victory hexes with units that have guns and if infantry unit have lost over 50% of their men, you cannot capture hexes with it. Also, you cannot capture hexes with size 0 units.
