How should members of military units pray on the front line?
Question

                How should Muslim soldiers pray when they are on the front line, guarding against the enemy, such as the Muslim troops in Pakistan who are guarding against the kaafir Hindu troops in Kashmir?
Praise be to Allah. 
          If the soldiers mentioned are in the place where they 
          live, and are not traveling, then they have to pray Jumu’ah and pray 
          the four-rak’ah prayers in full. But if they are traveling to the frontier 
          then they do not have to pray Jumu’ah and they can shorten and combine 
          prayers, because they do not know how long they will be there or when 
          their tour of duty will end. May Allaah help us all to do that which 
          He loves and which please Him.
