The US military has a major logistics problem for forward bases. Their plan for conflict with China, 'archipelagic defense', relies on prepositioning small, mobile land units in the 'First Island Chain' that runs along the Chinese coast through lots of small islands from Japan through Taiwan (probably without US forces directly on Taiwan), and then through the Philippines bordering the South China Sea. The land forces would use anti-ship missiles to contain the Chinese navy. But in contemporary warfare, with sensors everywhere combined with precision missiles and drones able to strike at long ranges, anything that moves is at great risk. After the shooting starts, logistics could be very difficult. Geothermal could solve much of that problem for energy, but I wonder how feasible it is to dig a hole for a temporary base. What if you're there for a month? A year?
