TacOps is a simulation of contemporary and near-future tactical, ground, combat between United States (US), Canadian (CA), and New Zealand/Australian forces versus various opposing forces (OPFOR). Most of the vehicles, unit organizations, and weapons utilized in today's world by these forces are present in the game. Some weapons and capabilities that are likely to be available over the next ten years are included as options, as well as some older organizations and weapons. The movement and interaction of infantry and armor units is treated with great detail. Supporting air and artillery activities are treated more conceptually. The primary simulation focus of TacOps is ground operations from the perspective of the battalion or regimental commander. You are a commander, not a gunner. Your control of weapons fire is limited to positioning your units with movement and disposition orders, setting minimum or maximum engagement ranges, and designating priority targets during the orders phase of a 60 second game turn. During the combat phase, your units will automatically choose their actual targets. TacOps is played in turns. Each turn consists of two phases: an orders phase and a combat phase. Each phase occurs simultaneously for both players. During the combat phase the units of both forces, under computer control, simultaneously carry out their orders for movement and combat in four, fifteen second pulses. You only observe during the combat phase; you can not give or change orders until the next orders phase. In addition, "fog of war" is simulated by showing enemy units only if they are in some friendly unit's line of sight and visual range. You may also choose to see all units at all times.
