An email I received from our RRRRRRRRRRRRRRRRRRWESO last night made me think. He asked for retention ideas and stressed: "All comments must be cost neutral". So, setting aside my belief that what he meant was 'free', I started wondering. I have come up with the attached model. It is a model and I am not interested in comments like 'the daily rate of pay is wrong'. I know - it is just a model. The question is, are the figures it provides believable? I have made a number of assumptions which can easily be changed (they are in red) around the cost of your training each year to the army, the number of days, the number of Op Tours and the amount of experience they are worth. Ladies and Gentlemen, your thoughts. msr v.2 added - corrected bug with selecting rank as 'Maj'
