CM, every one I ever served on.
In maritime individuals were dripfed into existing crews. I suspect I didn't make my point clear enough. Any sqn or crew with new personnel is, by definition, less than 100% ready.
A sqn, deployed and worked up with no rotation of crews or personnel will near 100%.
The Soviet model was a 3 sqn regt with one sqn fully experienced and the third 27th training crews.
Ps, the ones I was on were the continuous rotation of crews model.
