Military engineers against the migration: Long term experiences for the Hungarian Defence Forces from the deployment of engineer obstacles on the border against the mass-migration emergency

In the year of 2015 a serious mass of refugees arrived in Europe. In the second half of the year the daily number of the migrants started to increase rapidly and in few months vent up to 10,000. This huge, uncontrolled mass of people caused extreme administrative, humanitarian, border guard and police tasks to the involved countries. Hungary has started to build fences along its southern borders to stop uncontrolled and illegal border crossings. In our paper we start with the description of the types of military engineer barriers, than we describe the escalation of the 2015 migration events in Hungary. We present the “Crisis situation caused by mass migration” announced by the Government and the involvement of the Hungarian Defence Forces as collaborators. We summarize the related military tasks completed so far by the designated forces of the Hungarian Defence Forces and the occurred problems and gathered experiences. In the end of our paper we make some comments and proposals for the future that can be useful also for other countries.
