I've been playing a while but am new to these forums. So if anyone else has had this idea, let me know or direct me to the thread.
I was thinking of a "Squad Title" or "Squad Ability." The idea is it would be a single higher priced upgrade that applies to every ship in your list. My friends and I have tried some of these in friendly games and they can really change how certain ships work with each other. Some examples:
Unit Cohesion
Squad Title, 6pts
Your squad cannot have more than 5 ships and must not contain any large ships.
When one of your ships is defending, if 1 or more friendly ships are at a closer Range Band to the attacker than the targeted ship, then you may roll 1 additional defense die for each closer ship. (Adapted from Tactical Jammer modification and Biggs)
Thematically it simulates a flight of fighters that have practiced together and cover for each other during a dogfight by either blocking firing lanes or distracting the enemy. Note that it is measured by range band, so if 3 ships are at R1 of an attacker, none of them gets the bonus but a 4th ship at R2 would roll 3 extra dice if targeted. Picture an Academy Tie screen protecting some Bombers coming in behind them.
Combat Data Feed
Squad Title, 6pts
All ships in your squad must have an equipped Astromech or Salvaged Astromech upgrade.
When you declare an attack with a torpedo secondary weapon, if the defender has at least 1 red target lock token assigned to it, then you may ignore any instructions that require you to spend a target lock or focus token to perform this attack and you may reroll any or all of your attack dice. (Inspired by "Star Wars: Rogue Squadron" books.)
Thematically it would be similar to one ship 'painting' a target with a laser or radar signal and all other ships using that as a tracking signal for their ordnance to home in on. This gives you a way to get off ordnance on lower PS ships and to modify the dice without having to use actions or spend tokens.
I am not sure how these would fit MoV scoring for tournament play since the point cost is not attached to any one ship, but like I said, it can make for some interesting games.
