The proposals for adjustment of processes and equipment during a preparation phase of perspective deployment of mobile geographic support unit were created on a basis of author’s knowledge and experience, studies of documents and a discussion of participants in missions. The ISAF mission (currently Resolute Support mission) represents a model on which a future form of geographic support of national contingents in missions abroad is being developed. The brought up results represent a recommendation for further development of geospatial support of AČR in missions.
