During the War of Resistance Against Japanese Aggression, the comparison of the strength of a wing and a regiment was usually based on the military organization, combat mission, and regional characteristics to which it belonged. Therefore, the number of regiments that a wing is equivalent to is not a simple proportional relationship, but needs to be analyzed on a case-by-case basis.
First of all, it is important to understand that a wing is usually composed of several different arms, including infantry, artillery, cavalry, engineers, baggage, etc. Each class has its own specific tasks and responsibilities, and therefore plays a different role in combat. A regiment is usually composed of a single branch of the army, such as an infantry regiment, an artillery regiment, etc.
Secondly, it needs to be taken into account that there were great differences in the military organization during the War of Resistance Against Japan. Different armies, different regions, and different combat missions have different military organizations. As a result, the proportional relationship between a wing and a regiment will also vary depending on these factors.
Finally, to be clear, the strength of a wing is usually much larger than that of a regiment. Typically, the number of people in a wing is in the thousands, while the number of a regiment is usually in the hundreds. Therefore, during the Sino-Japanese War, a wing was usually equivalent to the strength of several regiments or even dozens of regiments.
To sum up, how many regiments a wing is equivalent to is not a simple proportional relationship, but needs to be analyzed on a case-by-case basis. During the Sino-Japanese War, the strength of a wing was usually much larger than that of a regiment, so a wing was usually equivalent to the strength of several regiments or even dozens of regiments.
The foreign famous cavalry wing has 452 personnel, 429 horses, 320 various guns, 672 engineering wings, 99 horses, 3461 baggage wings, and 2612 horse standard infantry wings (taking the third division at the beginning of the war of aggression against China in 1937 as an example) Establishment: 3 infantry brigades of 1,091 people, plus rapid-fire artillery squadrons, communication teams, transport teams, etc., the whole wing has a total of 3,747 people and 526 horses. It usually has jurisdiction over 2-3 artillery brigades of 688 people, 24-48 mountain artillery or howitzers, plus the wing headquarters, observation teams, and wing transport teams, a total of 2,000-3,700 people.
