用兵名义分型 / Military Justification Typology

Definition

用兵名义分型 / Military justification typology is Hanji 429’s framework, drawn from 魏相, for judging a proposed war by its purpose before judging its opportunity, scale, or tactical promise.

Current Synthesis

The concept arises when 汉宣帝 considers attacking 匈奴’s western region during the 车师国 crisis. Wei Xiang does not treat all force as equal. He divides armies into 义兵, which rescues the endangered and punishes violence; 应兵, which responds when attacked; 忿兵, which arises from anger over small grievances; 贪兵, which seeks land and wealth; and 骄兵, which displays force because a state is strong and populous.

The episode’s idiom claim turns on that last category: “骄兵必败” is not merely about overconfident soldiers, but about a regime using strength to show off. The typology therefore links military ethics to state capacity. Even a tempting enemy vulnerability should be rejected if the war’s name is anger, greed, or pride and if the people’s burden, border poverty, and internal disorder make escalation unsound.

Key Claims

• A proposed military action should be named by purpose before it is evaluated as opportunity.
• Rescue and defensive response occupy different moral positions from anger, greed, and pride.
• “骄兵” names force-display by a strong state, not just battlefield arrogance by troops.
• State capacity and popular burden are part of legitimate war judgment.
• The Cheshi case shows that limited extraction can be wiser than exploiting an enemy’s temporary distraction.

Evidence

Wei Xiang’s categories:

• Hanji 429 says Wei Xiang asks Xuan to clarify the expedition’s name before attacking Xiongnu’s west.
• Hanji 429 defines 义兵 as rescuing danger and removing violence, and 应兵 as responding to invasion.
• Hanji 429 defines 忿兵, 贪兵, and 骄兵 as anger-driven, gain-seeking, and strength-displaying forms that lead to failure or destruction.

Cheshi restraint:

• Hanji 429 says Wei Xiang cites Xiongnu’s recent release of Han captives, limited recent raiding, frontier poverty, and domestic disasters as reasons against major war.
• Hanji 429 says Xuan accepts the advice and sends Chang Hui to extract Zheng Ji instead of launching the wider attack.

Counterevidence & Qualifications

The typology is a source-scoped Wei Xiang / Han Shu framework as presented by the episode. It does not settle all theories of just war, all classical military terminology, or every later idiom use of “骄兵必败.” The source also does not argue that Han should never use force against Xiongnu; it supports a narrower claim that this proposed escalation lacked proper justification and capacity fit.

What Changed

• Created the concept from Hanji 429’s “骄兵必败” origin and Wei Xiang’s fivefold war-purpose classification.
