In Russia in the military reserve consist to 45-65 years (depending on rank). Paul served in the army and, in theory, has the rank of private soldier or junior commanders. He consists in a military reserve to 45 years. Theoretically, he can be called up for military assemblies annually. He can also pass retraining to improve military rank. But practically this is never done. I, having the rank of junior officers (sergeant), never called up for military assemblies. Most often are called upon for military assemblies reserve officers (to improve the professional skills), but also not every year. If Paul leaves the apartment every year in one and the same time, it is unlikely the military training.
