The German Embassy in Zagreb reported on Wednesday that the delivery of the vehicles, worth more than 600,000 euros, would take place tomorrow (22 December).
The donation has been granted within the Stability Pact for Southeast Europe.
Through such measures Germany offers support to Croatia's contribution to the stabilisation of the region, which is one of the most important routes for the transit of illegal migrants and smuggling in narcotics, weapons and human beings, the Embassy said in a statement.
In this way, Germany also backs Croatia's progress towards the European Union.
The embassy recalled that for the last five years, Germany had considerably supported the activities of the Croatian border police.
