Soldiering is the strength of soldiers and other resources associated with traditional warfare (ground and aerial vehicles, conventional weapons, tactics, etc.) in a particular race's army. Soldiering allows planetary invasion to be conducted in a more efficient manner, resulting in less friendly losses for more enemy kills. It appears to work by modifying the Advantage Factor of the race. After researching Stellar Marines it is possible to construct a Tir-Quan Training center, a Galactic Achievement which improves Soldiering by 25.
