Understanding how unit size is shown on map symbols matters. The base rectangle represents the unit type, and what sits above that symbol signals the echelon or size. A single vertical line above the rectangle is the marker used to denote a company-sized unit, so this symbol clearly identifies a company rather than a platoon, battalion, or higher unit. The other shapes convey different meanings: three dots above would indicate a different size or echelon, a rectangle with an X inside points to another unit category, and a diamond shape is not used for a standard company marker.

In a PACE plan, the letters map to four modes of communication: Primary is the best available method, Alternate is a different medium used if the primary fails, Contingency covers another backup, and Emergency is for immediate signaling if all else fails. The “A” stands for Alternate, the secondary path you switch to when the primary FM (UHF/SINGARS) isn’t usable. Using satellite-based communications (JCR/BFT) as the alternate gives a different transmission path and broader reach, bypassing the issues that can affect ground-based radios such as terrain, congestion, or jamming. This redundancy is precisely why satellite is the preferred alternate in many EXAM 2 scenarios. The other options describe non-primary comms or non-communication means (night-ops lighting, emergency pyro), which aren’t the alternate path in this plan.

Amplification at each echelon scales with unit size and the area it must cover. A battalion operates over a broader area and handles traffic from multiple companies, so its communications backbone needs a power- and capacity-rated amplifier that can sustain multiple links, route traffic, and maintain signal quality across the battalion’s area. The Battalion Echelon Amplifier is designed for that level, providing the necessary reach and capacity to support command-and-control across the battalion and to interface with higher echelons as needed. Smaller echelons—squad or section—don’t require or provide enough bandwidth and coverage for a battalion’s network, and a company-level amplifier handles only the company’s own traffic. So, the amplifier labeled for the battalion echelon is the correct one.

In FARPs, the most serious risk is the fire and explosion potential from handling aviation fuel in close proximity to weapons and aircraft. Fuel spills, leaks, or improper fueling procedures can ignite, and with munitions nearby the consequences can be catastrophic, so strict control of fueling operations is essential. This requires grounded and bonded fueling to prevent static discharge, designated fueling areas away from explosives, immediate spill containment and cleanup, readily available fire suppression, and trained personnel following clear procedures. While weather delays, administrative paperwork, and security measures are important, they do not pose the same immediate, high-consequence safety threat as fuel-related fires in a temporary, high-tempo environment.
