suicide attack the boko haram deadliest weapon of mass destruction

suicide attack the boko haram war in Nigeria, Cameroon and Chad. How an army deal with suicide bomber? what should these governement do to stop the attacks?

Nigeria tried to send more troops in the north to stop the attacks. cameroon follow the same movement of troops. But yet we are waiting to see the positive results. is this approach effective dealing with terrorist? boko haram have no real army but people attach to their cause. It is working for them very well. You have nationals armies with armoured cars. The support of intelligency and the police beating up by mere bandits. suicide attack like any other technique have something we can use to stop. I therefore think than the armies of Nigeria, Cameroon and all neighbouring countries. should work hard and come up with the formula. Not with heavy artillery as we’ve seen that does not work.
We can give idea here to say how we can stop suicide bombing in Nigeria or Cameroon. We can seek advice to the US of America and other countries.
