"The shocking order has been given as it emerges British ministers have warned Russia is making the situation in the Middle East much more dangerous.

RAF jets will be armed with advanced short range air-to-air missiles and British and Nato pilots have been told to fight for their lives if they are fired upon by Vladimir Putins air force. "

I personally think any attack on Britain would be moronic, not to mention the potential catastrophe as Nato and the USA would counter attack along with the UK

Russia The largest collection of Tanks than any other country. One of the biggest armies and reservists. Has the most nuclear warheads than any other country. Some of the best military trained tactical force. Russia alone could take over half of the worlds countries by just overpowering them with there mass military.

ChinaRussia's closest allie's is an up and coming superpower, that is said to overtake USA by 2020 as the biggest economy on the planet. They are spending more and more each year on their defence budget, and will soon overtake USA'S years spending by far. They all ready have the largest population on the planet, thus, the largest land army at their disposal. China has been heavily investing in military technology and have increased their military power by ten fold in the past 15 years. They will soon become the main threat, and Russia being their closest allie is a scary though for the future.

United Kingdom Has the most technologically advanced military on the planet, Only USA comes close ( Very Close). Thanks to Lockheed and BAE systems ( A UK contractor company ), the united kingdom can rely on there superior Tanks, Fighter jets, Missiles and army based weaponry. Even a lot of USA'S tech comes from Lockheed and BAE Systems. This is where the UK come into there own. They don't posses the numbers compared to USA, Russia and Chine, as it's just not possible on small island. How-ever, what comes less, comes more powerful. The UK make their numbers up by making some of the most powerful war machines on the planet, take the Type 45 Destroyer that has just come into service. IT is the most technologically advance destroyer on the planet, it's nearly impenetrable due to the computer/robotic defence systems in place that can destroy up to a 1000 objects ( missiles or enemy aircraft ) at any given time up to 1 thousand miles away and is coated in special coating that makes them undetectable. It can also carry nuclear warhead. There are a total of 5 that will be in operation by 2017, each costing over a billion pound.
The UK also posses 4 nuclear trident submarines that are undetectable by reader and always patrolling the seas just in case we need to fire a nuke at someone. No one but the servicemen on board, the prime minister and the General know it's location at any given time.The UK also has the best tactical force in the world ( SAS ) and some of the best trained a well equipped army on the planet.

USA

The USA has some of the most technologically advanced military on the planet, only slightly surpassed by the UK. With USA being one of the biggest countries on the planet, they also have the numbers and financial power to spend big on there defence budget. That being said, currently they are by far, far the most spender when it comes to military spending each year, although that will change within the next 3-5 years when China comes into play.

USA has some of the largest collection of tanks, man power, missiles, nukes, aircraft and navy. USA alone could take on most if not all countries ( besides a USA vs RUSSIA and Chine war ) The USA would need the United Kingdoms and NATO'S help for that.

The USA'S marines are also some of the best tactical force in the world.

Who would win?

Russia and Chine vs USA And UK?
Or UK and USA vs Russia and China?

I personally think the Technology of the UK and the power of the USA would be to much for anyone.
