Which statement below best describes the advantages and disadvantages of leasing commercial satellite channels to support military communications?

• A. They have ample bandwidth providing high throughput, but they are in high demand to support commercial users, so it is difficult to get channels on commercial satellites.
• B. They have ample bandwidth providing high throughput, and they are highly protected against jamming and intercept, but commercial bandwidth is hard to get because many vendors refuse to lease to military users on ethical grounds.
• C. They have ample bandwidth providing high throughput, but most commercial satellites do not operate in orbits conducive to supporting military communications.
• D. They have ample bandwidth providing high throughput, and they provide capabilities for communications on-the-move (COTM), but they have no protection against jamming or intercept.

Answer: (A)

Leasing commercial satellite channels for military communications emphasizes a practical tradeoff: you can access large, high-throughput bandwidth, but you must contend with a crowded commercial market for those channels. In other words, the capacity exists, but securing dedicated channels can be difficult because many civilian users compete for the same satellite resources, driving competition, scheduling challenges, and cost.

Other ideas in the choices either overstate or misstate realities. Protection against jamming or interception isn’t inherent to commercial satellites and typically requires additional security measures and design choices; claims about ethical refusals by vendors aren’t reliable barriers in practice; and while some systems can support mobility, not all commercial satellites offer seamless communications on the move. The core, most accurate picture is the combination of ample bandwidth with the reality that access is limited by high commercial demand.
