Here's my concept for an event focused around capturing and defending installations.
Round 1: Standard 4x4 foot table, 8" deployment zones, 750 MFV naval and air forces. At the center of the table is an island at least 6" in diameter with a bunker at the center. The bunker has nominal defense of only 1 AP. At the time limit or the end of 4 turns the player with AP controlling the bunker (as a prize) wins the round. Player controlling bunker at end scores 1 Control Point. 90 Minute Limit.
Round 2: Players which won Round 1 remain at the same table and place reinforcements, a bunker with guns and stats according to their faction at the center of the board. Then the defending player deploys 600 MFV naval, ground, and air force to defend the bunker. Randomly determined opponent deploys 750 MFV naval and air force within 8" deployment zone on one edge and attempts an assault. Player controlling bunker at end scores 1 Control Point. 90 Minute or 4 turn limit.
Round 3: Players winning Round 2 have dominated their sea zones and move to assault the enemy's home port while players losing Round 2 are designated as defenders. Defending player sets up 1000 MFV naval, ground, air force along one table edge which features a coastline, buildings, and defensive installations (included as part of the 1000 MFV). At least 3 installations are placed along coastline, each one worth 1 Control Point. Assaulting player deploys 1250 MFV naval and air force along opposite table edge. 2 hour time or 4 turn limit. Each player scores Control Points for having AP on an installation or the only active models within 4" of the installation.
Players may earn a maximum of 5 Control Points by winning the first 2 scenarios and capturing all 3 installations in Round 3, and a player losing one of the first two scenarios could still capture all 3 in the final round and win if the leading player doesn't do well in the final round. This format provides all players a chance to take the lead position.
