Actions:
Portrait - Show (Cinematic portrait at Center Left) for (All players) (Do Not force visible)
Transmission - Send transmission Battlecruiser_Ready from (Model Portrait - Battlecruiser) using (Cinematic portrait at Center Left) (Add 3.0 seconds, Don't Wait until it finishes)
General - Wait 8.0 Real Time seconds
Portrait - Hide (Cinematic portrait at Center Left) for (All players) (Do Not force visible)
