Note that you have somewhere between three and thirty seconds before things go seriously sideways. You don't have a lot of time to shout directions, so you'll need to keep it very concise. You may feel free to use any code-worded battle plan that the team has used in the past but it is extremely unlikely that we will retroactively create any others.
@faflec can undoubtedly provide a better list than I can, but here are the ones I know offhand:
White: do not engage, absolutely no damage to the opposition if they engage, do not stop to rescue teammates
Yellow: do not engage, minimal damage if engaged
Green: minimal damage [this one wasn't actually used but I'll give it to you]. Does not specify engage / do not engage; that would be stated separately
Black: prefer lethal force. Does not specify engage / not engage
These may be joined with a target: "Green sword guy!" or "Black Rock team!"
Specific plans:
Shell [Game]: pop clones, swap places, run for it. "Shell Black" would mean run but kill anyone who gets in your way
Snake Bite: <not relevant as it relies on Mari-sensei's genjutsu abilities>
Tsunami: Alpha strike the biggest opponent, then run. Assumes 'Black'
Earthquake Black: Kill everything that moves and isn't on your team, blow anything that isn't moving into splinters. (No, there is no 'Earthquake <any other color>')
Black Flag: Pick the target you think you're best suited for, kill them, then go support the rest of the team.
Callsigns:
Whiskers: Hazō
Spearfisher: Keiko
Collie: Akane
Fish: Noburi
EDIT: Fixed Keiko's callsign.
