Tactics are the part of the military problem solving, which attempts to address situations that arise in a concrete context and in a specific geographical area. It is about learning to perceive both the more stable geographical conditions in the working area as well as taking into consideration the effects of climate and weather and how the squad and their systems are affected and how an opponent could try to exploit these conditions and turn them to his advantage. The idea in tactical training is therefore to be able to master both the battlefield environment with its limitations and possibilities and the combat that is conducted there. Friction is used as a concept in several discussions about military activities. The geography with its sometimes channelling terrain and various landscape elements can constitute serious obstacles in trying to carry out all the tasks and abilities expected of a unit. Geography, Climate and Weather can thus be regarded as frictions in a military operation. This should also be possible to train in simulators and systems for war gaming.
