Bad idea.
In economics, free markets beat state controlled markets at least partially by allowing the best and brightest people / products /services to raise to the top.
Similarly, by controlling individuals by installing lifetime assignments these best and brightest are restricted from advancing into the positions where they can do the most good.

Furthermore, I bet the benefit coming from a unit serving together is logarithmic in nature. That is, a unit serving together for 6 months is much worse than a unit together for 2 years. But that relative difference is much smaller for between units serving together for 10 years and 20 years respectively.
