In most jurisdictions, collision coverage is optional unless there is a lien holder on your vehicle. If you don't have collision coverage, you are going to be on the line for the costs to repair any damages to your vehicle in an accident caused by you, including damage to your side mirror.
Tactical planning is such an important part of a company's strategic planning process that management consulting companies are often hired to assist companies in preparing tactical plans. A company usually begins with its objectives and then develops strategies for how to carry out their objectives.
Military tactics are the science and art of organizing a military force, and the techniques for combining and using weapons and military units to engage and defeat an enemy in battle. Changes in philosophy and technology have been reflected in changes to military tactics. In contemporary military science, tactics are the lowest of three planning levels: (i) strategic, (ii) operational, and (iii) tactical. The highest level of planning is strategy: how force is translated into political objectives by bridging the means and ends of war.
