So in other words, you have no idea what the MOD is do you?
In the most literal sense of the word, the MOD is the organisation which encompasses the 3 armed services, their reserves and the civil service.
The MOD as an organisation is essentially filling the roles of the strategic HQ which oversees the command and control, and direction of the armed forces, sets out their requirements and priorities and administers them.
The HQ element of the MOD (i.e. Main Building, DE&S etc) is mainly staffed by military officers who are posted in on 2 year tours, often from front line tours and often returning to front line tours. There is a civilian element to support them, but your idea that the MOD is somehow an organisation full of civilians trying to hamstring 'our brave boys' who only exist on the front line is so far from the truth as to be laughable.
Staff requirements are drawn up by military officers, based on their professional understanding of the needs and requirements of their service. The RN has never had a staff requirement to convert a merchant ship to a V1 carrier, and neither has any other armed force in the world. Why are you not getting the hint that its not 'closed thinking' thats preventing this, but that its a really stupid idea with no practical military value at all?
You really must stop believing all you see in the Daily Mail and other places because , its not usually true...
