The experience of carrying out combat (service-combat) tasks by various components of the security and defense sector in the initial period of the russian-Ukrainian war points to the need for reliable protection and defense of military units (objects), the basis of which is the planning and implementation by operative response forces of measures aimed at for complete neutralization or reduction of the negative impact from the actions of the enemy's subversive forces.
In order to ensure high-quality planning of the protection and defense of the object (objects) of the military unit, commanders (chiefs) need to have an appropriate tool to support informed decision-making, namely a mathematical (calculation, analytical) apparatus that will make it possible to predict events under certain conditions. which may occur in the event of an enemy attack and determine effective measures for maximum preservation of the integrity (combat capability) of the protected objects.
The article presents a spatio-temporal model for determining the possibility of timely countering the enemy with the forces and means of the observation post of the security unit, which is based on the solution of the spatio-temporal problem, and, unlike the existing ones, takes into account: the fire capabilities of the observation post and on-duty forces; maneuverability of the main (regular) forces of the security unit; mutual placement of the enemy in relation to the observation post and security facilities, as well as the main (on-duty) forces of the security unit.
In the future, the model proposed in the article can be used as an integral part of the methodology for determining the rational composition of forces and means of protection and defense of military units (objects). Also, this tool can be implemented in the educational process.
