The Croatian Army is responsible for implementing war operations independently and with the support of other branches, leading the fight on land, on the coast and on the islands.

In 2007, the Croatian Army abandoned the corps structure and the territorial principle of defense through a reorganization, and from four brigades two were established with their commands in Vinkovci and Knin.

For such an organizational structure to work, it must be deployed with high level of training and equipped with modern weapons systems that put emphasis on precision, quick mobility and interoperability with other NATO partners.

The Home Guard was restored and became a separate part of the Croatian Army as a reserve unit and was subjected to a unique command system.

After Croatia had only active units of a total of about 16,000 people for several years after joining NATO, in 2014 it was decided to start re-organizing the reserve component.

In 2020, the Chief of Staff of the Croatian Armed Forces, Robert Hranj, spoke about plans to establish a certain operational reserve in the coming period whose units will be smaller, but will be characterized by a higher degree of readiness and develop the ability to perform all types of tasks, from supporting civilian institutions in the entire territory of the Republic of Croatia to combat tasks.

Due to Russo-Ukrainian War and intense regional security it has become apparent current Army organization requires significant re-organization.
