The necessity of systemic confrontation training is sketched, and the artificial system construction, computing experiments and parallel implement in systemic confrontation training are preliminary modeled and analyzed through the artificial systems, computing experiments, parallel implement (ACP) methods of parallel system theory. The result shows that the elements of actual system should be projected to virtual battle space to construct artificial system (natural elements and troops should be projected via digital twin technology and agent based simulation method respectively), so that warlike operations effect can be projected easily. Solutions to construct practicable systemic confrontation training system are given from preliminary exploration on how to carry out computing experiments and how to execute parallel implement in systemic confrontation training.
