Gum....
You have any Mil-background to back that up???
Not quite the "Loose Deuce" that "I" was taught..........
There are two uses of the term Loose Deuce.
One is a formation, the other is a wing pair tactical doctrine.
Examples of other wing pair tactical doctrines are welded wing and double attack.
Loose Deuce as tactical doctrines requires a wing pair that are very experienced flying together but it is an extremely effective. The essential difference between Loose Deuce and Double Attack is the engaged fighter is not the primary shooter. His focus is on pressuring the bandit into a predictable flight path so that the free fighter can set up a blind side guns pass.
Loose Deuce is described by Shaw to be a variation of Double Attack in which the free fighter isn't responsible for defensive lookout. Instead each fighter takes responsibility for defensive lookout.
Shaw describes Loose Deuce tactical doctrine on pages 215-219 of his book.
I've used loose deuce for years (10+ now) with much success online. Most of the time has been without the participation of my wingman. Its very hard to get an online guy to the required level to fly proper Loose Deuce. But its very easy to employ in an arena without active participation of the wingman.
The classic arena engagement generally involves on or more friendlies tailchasing a bandit in an essentially co-energy state. A position high (about one vertical turn radius)a bove this fight puts me in position for a classic loose deuce guns pass. The bandit begins a turn in his evasives and the loose deuce fighter works for a high belly side guns pass. Loose Deuce is very effective against a bandit who hasn't reached panic level evasives. If his is already panicked into last ditch evasives he will be too unpredictable for this particular doctrine.
I'm assuming you are referring to the formation called "Loose Deuce" and not the tactical doctrine.
