Each EU MS located at the EU external borders is responsible for the management of their borders, thus it is a national obligation to proceed with necessary actions to prevent crisis situations and to respond with the available means effectively, at an early stage, at its borders. Migration flows can increase rapidly leading to security incidents difficult to be managed, therefore personnel on the ground for migration management is required. This is described with capability gap 2.CGF.24. In addition, the development of Rapid deployment teams with certain capabilities and skills (translators, social workers, medical staff) will assist BGAs to better respond to high migration flows.
