Nobody can say that he lacks range.

Yevgeny Prigozhin had the world at his fingertips on Saturday. After weeks of veiled threats, the Wagner Group leader declared an armed rebellion against Russia's leadership in Moscow.

In the early hours of Saturday, surreal images showed Wagner forces pushing into the southern city of Rostov-on-Don, supposedly en route to conquer Moscow. Armoured vehicles trawled the streets and helicopters swarmed in the skies.

It was an unconventional coup. Prigozhin was a close ally and friend of the president, handed the monikerA name. "Putin's chef" for his time catering for the Kremlin - though he prefers "Putin's butcher".

And he ultimately abandoned his insurrection very suddenly despite failed negotiations with Putin and insults from both sides. He exited Rostov-on-Don with aplombSelf-assurance and poise in a tense or difficult situation..

Much remains unclear, but one thing is clearer than ever. The Wagner Group's close relationship with the Kremlin, which Putin has always denied, was always an open secret. But now, after this very public melodrama, pretences at the group's independence have been abandoned.

With an estimated 40,000 of its 50,000 army made up of convicts who traded prison for the barracks, the Wagner Group has been accused of human rights and democratic abuses in various countries in Africa, the Middle East and the BalkansA region of southern Europe, south of Austria and Hungary. It was traditionally seen as the meeting point between the Christian and Muslim worlds..

The notion that a private military contractor can wield such power over world events is, for some, very sinister. But modern mercenariesProfessional soldiers who are hired to fight in an army. are booming. The largest private military giant, G4S, is the second largest private employer in the world, only surpassed by Walmart. There are at least 150 military contract companies in the world.

What does it mean that we have put war on the market? For some, private military contractors have the same advantages as any other private practice: they can be more efficient, more responsive to changing demands and needs, and can contribute vitally to global intelligence.

But there are valid concerns too. If a hot dog maker can almost launch the 21st Century's most explosive coupWhen an individual or group takes control of government by illegal means, including by violence., what other hell could private militiaA military force made up of ordinary citizens rather than professional soldiers. wreak?

Yes: It is unethical to impose a profit motive on killing, bombing and maiming. Private military companies may be "more efficient", but it will always be in their interests for conflicts to continue so that the money keeps rolling in.

No: We hear little of private armies because they can carry out covert missions and intelligence-gathering, as well as targeted military actions, very efficiently. They are not all as unruly, violent and bloodthirsty as the Wagner Group.

Or... What happened with Prigozhin should serve as a warning to us all that there is a reason that we put elected public figures in charge of our military, and not hot dog-wielding madmen. But at the same time, Russia's despotic leadership created the conditions for Prigozhin to launch his coup - it could not happen in a democracy.
