Logistics Basic Officer Leader Course (LOG BOLC) Exam 2 Practice

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.
