Thanks
Cougar, that makes sense.
The treatment of the junior guys is just as important as the bonuses to the senior guys looking at leaving. You can't treat people like dirt their whole career and expect them to stay on +5 yrs with a magical bonus at roso.
Shagpile's post seemed to suggest he didn't consider this a reasonable approach, hence my query.
As for the choice between the options, I guess it depends on whether you're deployed at the 15 year mark or not
