Capital Defense Mobilization / 都城防卫动员
Capital defense mobilization / 都城防卫动员 is the late-Qin state-capacity pattern added by Qinji 128-5. The source argues that 胡亥 / 秦二世 cannot be reduced to pure inaction because he had earlier recruited fifty thousand brave soldiers into 咸阳 and trained them in mounted archery.
The concept matters when 周文 approaches the capital. His army is numerically huge, but the episode contrasts its weak training and battle experience with Qin’s capital guards, trained soldiers, and emergency use of 骊山刑徒应急动员. In that setting, defending a capital is not just a city-wall problem; it is the concentration of guards, trained manpower, officials, nearby labor populations, and command authority.
The source still treats Qin Er Shi’s rule as deeply destructive in the broader Qinji 128 chain. This concept only records the narrower corrective: a failed ruler can still command enough residual state capacity to stop an overextended rebel army near the capital.
