The offensive began under cover of darkness
   |     Afghanistan conflict an 'information war'  | 
        |   By Jonathan Marcus  BBC  News diplomatic correspondent   |    
   It's called shaping the battlefield. It's not the traditional air  onslaught or artillery barrage designed to weaken an intended enemy before the  offensive goes in.          Nato is keen to portray an image of co-operation and  camaraderie  |    Instead it's now about shaping the information battlefield, because in  Afghanistan - and in modern warfare in general - information has become the new  front line.   At the very heart of Nato and the Pentagon, the disciples of the new art of  "strategic communications" know that perceptions matter.   Nato's top commander in Afghanistan, Gen Stanley McChrystal, made this point  explicitly in a recent interview.   "This is all a war of perceptions. This is not a physical war in terms of how  many people you kill or how much ground you capture, how many bridges you blow  up. This is all in the minds of the participants."   Any information you send out carries with it a variety of messages.   'Telegraphed'  Take the current operation in Helmand. It has been broadcast widely in  advance. It even has a not-so-catchy title: Operation Moshtarak, which in Dari  translates as "together".         Gen McChrystal has called the Afghan conflict a "war of  perceptions"  |    So there you have it, already three messages, if not more.   The operation's title is in a local language and it stresses the idea of  partnership - doubly signifying that this is a joint operation between Nato and  Afghan government forces doing the job "together".   The advance warning too sends a crucial signal - it is part of a deliberate  and explicit strategy to encourage civilians to take precautions; to calm and  inform tribal leaders; and perhaps to encourage some Taliban fighters to make  themselves scarce.   "This operation has certainly been telegraphed in advance far more than  previous operations," one Nato insider said, "but the alliance has been doing  this kind of thing for some time.   "The message is clear. We are determined to take the area, but in such a way  as to minimise violence", the official said. "But if we have to fight for it, we  will win."   'Psy-ops'  That sounds just a bit more like the traditional kind of message you would  expect at such a time, but the reality is that on the information battlefield,  just as in operations on the ground, things have changed dramatically.   What began as inducement or encouragement for troops to lay down their arms,  or basic instructions to civilians not to get in the way of military operations  - think leaflets dropped by aircraft in World War II - has blossomed into almost  a social science of cause and effect.   Psychological operations or "psy-ops" of the 1950s have morphed into  information warfare.   There have been uneasy debates about where the boundary line between this and  the traditional press officer's role should be, because, let's face it, the  media is an involuntary actor in this drama too.   However the new discipline of strategic communications seeks to go beyond  information operations, press briefings and leaflet drops. It is, in the words  of one alliance official, "an over-arching concept that seeks to put information  at the very centre of policy planning."   When you are fighting wars within communities in an effort to secure popular  support for one side or another - the traditional struggle for hearts and minds  - you can see how central the concerns of the new strategic information warriors  have become.   In some ways, this is at the very core of modern counter-insurgency strategy.    'No hiding'  However there are limitations, not least those related to the ubiquity of the  modern mass media.   As Michael Clarke, director of the Royal United Services Institute in London,  said: "Strategic communications can only ever give out one message. They've  tried in the past to put out split messages and it doesn't work."   So much of what people hear in Helmand province, they also hear in Britain  and in other troop-contributing countries.   "There's a positive side to this," says Mr Clarke, "It's a consistent  message, but the danger is that if things on the ground get messy, there will be  no hiding from it." The information frontline is in effect everywhere.   This growing centrality of information and the need to shape perceptions  inevitably prompts critics to suggest that this is all not so new after all -  isn't it just one huge propaganda exercise writ large?   Not surprisingly, one of the new Nato information warriors disagrees.   "In strategic communications, the messages you are sending must fit the facts  on the ground," he says. "The discipline is about bringing perceptions and  reality together to achieve an effect."   'Untidy end'  Many critics may remain unconvinced seeing the whole thing as a giant  spin-machine intended to accentuate the positive and present one particular  carefully-controlled narrative of events.         Advance warning has been sent to Taliban leaders and  militants  |    Because that, in a sense, is what is at stake - it is a battle for the  narrative.   Whose interpretation of what is happening is going to prevail? This new focus  raises uncomfortable questions for anyone involved in the information business.  Perceptions matter in another way too.   There is unlikely to be a tidy end to the Afghan conflict. Nobody really can  define what "victory" or "defeat" in the traditional sense might mean.   So if it is to be an untidy conclusion then what people think about it - how  they judge the outcome - really does matter.   It used to be said that: "Britain won its wars on the playing fields of  Eton."   But now a new kind of warfare means that the information battle has to be  fought on multiple fronts by multiple actors.   From the fields of Helmand to the small towns of Kansas; from the tribal  areas of Pakistan to British cities where voters are girding themselves for a  coming election, the news from the Afghan battle-front will shape perceptions -  and these perceptions will inevitably shape future policy  | 
-led forces say they are making good progress hours after  launching the biggest offensive in Afghanistan since the overthrow of the  Taliban in 2001. 
There were clashes as more than 15,000 US, UK and Afghan troops swept into  the Helmand districts of Marjah and Nad Ali in a bid to secure government  control. 
 The Afghan regional commander said 20 militants had been killed. Two Nato  soldiers are confirmed to have died. 
 A Taliban commander reportedly said his men were retreating to spare  civilians. 
 Operation Moshtarak - which means "together" in the local Dari language - is  being led by 4,000 US Marines, supported by 4,000 British troops, with  Canadians, Danes and Estonians. 
 'Heavily booby-trapped'
 The BBC's Frank Gardner, with Nato forces at Kandahar airbase, says the test  of the operation's success will not be on the battlefield. 
       |    AT THE SCENE    Ian Pannell BBC News, Nad Ali  It's been a very successful day for British forces. They were  able to move into several key villages and establish a foothold.   Broadly speaking, they met little resistance. There was sporadic gunfire. One  RPG was fired over the location where we are based.   It's fair to say that the Taliban decided to move out of the district. Many  civilians have also left, and the challenge in the coming days and weeks is to  persuade them to come back, to establish meaningful security and then allow  meaningful governance to take place.  What will make a difference is if there is meaningful security established  and if the local people feel confident enough to place their faith in local  security forces.  This is an operation that has only just begun and it will take weeks and  months before we know how successful it has been.   Operation Moshtarak:  Diary     | 
 It all depends on whether the coalition can hold the ground and bring lasting  security and good governance to the population of central Helmand. 
 A spokesman for Nato's Isaf force has confirmed to the BBC that two soldiers  have been killed in Operation Moshtarak. 
 One died in an improvised explosive device (IED) attack and another from  small-arms fire. No further information has been released on the location. 
 Three US soldiers were also killed by an IED, Nato said, although it is not  clear whether they were part of Operation Moshtarak. 
 Mohammad Zazai, commander of Afghan troops in the operation, said: "So far,  we have killed 20 armed opposition fighters. Eleven others have been detained."  The casualties and captures were in separate incidents. 
 Troops have been advancing carefully, picking their way through poppy fields,  trying not to set off Taliban bombs. 
 A canal bridge into Marjah was so rigged with explosives that US Marines had  to erect temporary crossings to reach the town, reports the Associated Press.  
 Helmand Governor Gulab Mangal told a news conference the Taliban had "heavily  booby-trapped the area". 
 Marjah resident Abdul Wahaab told AFP by telephone as he and his family left  the town: "We were sleeping when all of a sudden we heard this horrible noise -  it was helicopters bringing in soldiers. 
 "As we were crossing the village we saw US and Afghan soldiers on the  junctions. There were lots of them." 
 Afghan President Hamid Karzai, who approved Operation Moshtarak, warned  troops to avoid civilian casualties, and called on Taliban fighters to lay down  their weapons. 
 Nato says Marjah is home to the biggest community under insurgent control in  the south. 
 'On the hop'
 It was estimated there were between 400 and 1,000 militants based there  before Operation Moshtarak was launched.

 Marjah has also long been regarded as a linchpin of the lucrative network for  smuggling opium - the raw ingredient used to make heroin - harvested from  Helmand's poppy fields. 
 Nato Commander Maj Gen Nick Carter told the BBC the offensive had been "so  far extremely successful". 
 "Indeed it would appear that we've caught the insurgents on the hop - he  appears to be completely dislocated," he said. 
 Later at a Ministry of Defence briefing in London, Maj Gen Gordon Messenger  said the UK force of more than 1,000 troops had secured their "key objectives"  at the start of Operation Moshtarak. 
 The offensive began with waves of helicopters ferrying US Marines into Marjah  in the early hours of Saturday. 
 British troops then flew into Nad Ali district, to the north, followed by  tanks and combat units.

 The BBC's Ian Pannell in Nad Ali says the vast majority of villagers seem to  have left the area to avoid getting caught in crossfire between the Taliban and  Nato troops. 
 Mullah Mohammed - a Taliban commander in Marjah - told ABC News that his men  were pulling back to spare any civilian casualties. 
 "We found civilians in massive danger so we decided to go backward just to  save villagers' lives," he said. His claim cannot be verified. 
 Nato had distributed leaflets in the Marjah area warning of the planned  offensive in a bid to limit civilian casualties. 
 It is the first major offensive since US President Barack Obama ordered a  "surge" of 30,000 extra troops to Afghanistan in December. 
 More than 1,900 Afghan police will provide support after the initial military  operations end, and a large team of Afghan administrators has been assembled.  
 The operation is part of an effort to secure a 320-km (200-mile)  horseshoe-shaped string of towns that runs along the Helmand River, through  Kandahar and on to the Pakistani border. 
 The area holds 85% of the population of Kandahar and Helmand.
