A ten-point plan has been presented by committees of German deputies which ask the government and European partners to implement a joint European army.
Germany's federal government supported the initiative but said it could be a long-term goal.
According to Russian news service Sputnik, German politician Elmar Brok said cooperation of national armies would “create significant synergies and added value in financial and defence-political terms.”
The idea of creating a single army has been repeatedly in EU agenda. 60 years ago, there had been a plan to form a European Defence Union but the attempts failed.
European Commission President Jean-Claude Juncker proposed in March to create a single European army to cope with the threats posed to member states and neighbouring allied countries.
Juncker said that the demands for forming a single European army is connected with the breakdown of relations between Russia and the West, who have been at odds over the crisis in eastern Ukraine.
A large majority in the United Kingdom, however, is opposed to the forming of a unified army, a United Kingdom Independence Party (UKIP) spokesman told Sputnik, adding that every sovereign state must have its own independent army.
