Final answer:
A fire plan with three or more company fighting positions typically involves overlapping fields of fire and considers various tactical elements such as weapon types and terrain. It correlates with military strategy principles of maintaining a strong defense and capitalizing on offensive opportunities as advised by Sun Tzu in 'The Art of War'.
Step-by-step explanation:
When drawing three or more company fighting positions, the fire plan that is indicated usually involves creating overlapping fields of fire to ensure that the area can be effectively covered and enemy movement can be intercepted or halted. Such plans are critical in military strategy to maintain a strong defensive position or to prepare for an offensive attack. These plans take into account various factors, such as the types of weapons and ammunition used (as referenced by the difference between using a liquid fuel/oxidant mixture and a solid mixture, the latter being more powerful), the terrain, and the expected avenues of enemy approach.
In the context of Sun Tzu's 'The Art of War,' the concept of attack by fire is metaphorical in general strategy, suggesting multiple ways to challenge an opponent. However, in the modern military, fire plans can be quite literal, involving coordination of small arms, artillery, and other weapons systems in a cohesive and strategic manner to optimize the combat effectiveness of a unit. Furthermore, the principle of using direct and indirect methods of attack reinforces the importance of a well-thought-out fire plan that leverages both overt and covert tactical maneuvers.
The act of planning and executing such coordinated fire is also intended to provide an advantage, as Sun Tzu emphasizes striking at a favorable moment rather than waiting for the enemy to make a move. The ultimate objective is to outmaneuver the opponent and secure a decisive victory while minimizing one's own vulnerabilities.
