All I was really meaning to point out is that the quote you posted can be interpreted in a number of different ways. I am not accusing the MoD of deliberately pulling the wool over anyone's eyes. Nevertheless, the quote says that those who choose to remain on AFPS75 will not be affected by "these changes". Do those words refer to the "Changes in UK Tax Law", or to "the introduction of the Early Departure Payment Scheme". None of us can be quite sure which of these two meanings, or another, the writer intended to convey. And, in the end, the MoD cannot, and will not, give a cast-iron guarantee that tax law will not change in the future in a way that it cannot foresee now. Be very careful, therefore, not to assume that the words are a legally watertight way of saying what you would prefer them to mean.
