an increasingly frustrated Army was desperately calling for better equipment, only to be rebuffed by "penny-pinching" ministers.
As you point out, this is incorrect. Once again we are reminded of the real enemy. The uniformed side (as opposed to the Civil Service side)of the Minstry of Defence has only one enemy, that is government and its front line troops, at the Treasury. It fights to maintain its funding and pet projects. As anyone who has served there knows, those lower down have to fend for themselves as they are not fighting the "real" war of politics.
Just to confuse the situation, there is a secondary war being fought at a slightly lower level, and that is between the three services. The man at the front line has no chance. I think you sort of touched on this in your book.
Tell me, someone, that it has got better since I left the military, 10+ years ago? Those I keep in touch with suggest that it hasn't.
