@BlackArmorTails ...what are you talking about? Tango Line isn't a thing on Earth, nor have we seen anything to suggest it's in Infinity. Single Line is the nickname for Ridgeback Squadron when they're all together in formation. You can see this from the Stonehenge gameplay. The quote is, indeed, "Single Line's murdering us!" The voice saying it is unknown, so we can't say for sure who was saying it at this time.
