Which FIST employment option ensures most platoons in companies or troops receive a forward observer?

The option that ensures most platoons in companies or troops receive a forward observer is the Platoon Forward Observer. This employment option designates specifically trained personnel within each platoon to act as forward observers, allowing them to directly coordinate and request fire support from artillery or air assets in close proximity to the battlefield.

Having a forward observer integrated into each platoon enhances the unit's ability to effectively communicate and execute fire support operations. This structure is crucial for maintaining timely and accurate support, especially in dynamic combat environments where quick responses to enemy threats are necessary.

While the other options such as the Battalion Fire Support Team or Company or Troop FIST can provide support, their deployment may not guarantee that every individual platoon has dedicated forward observer capabilities. Thus, the employment of a forward observer within each platoon is the most direct method to ensure comprehensive coverage and immediate access to fire support resources for each unit.
