set_air_oobCOUNTRYnoneRegisters an Order of Battle (OOB) file to be loaded for a country at game start, replacing any previously registered OOB (with key "air") on that country.
Only intended to be used within history files.
Example:
set_air_oob = "ENG_1936_Air"

set_air_oob 主要用于在 mod 中为某个国家指定一套独立的空军战斗序列文件，常见于新增历史开局、替换默认空军编制或为自定义国家分配初始空军单位的场景。例如，当你为某个 mod 新增一个 1936 年开局的法国强化版空军时，可以在该国家的历史文件里这样写：
# history/countries/FRA - France.txt
set_air_oob = "FRA_1936_Air_Enhanced"
对应的 OOB 文件应放置于 history/units/ 目录下，文件名与字符串完全对应。
[set_air_oob](/wiki/effect/set_air_oob) 与 [division_template](/wiki/effect/division_template)：空军编制文件往往需要配套的装备与模板定义，两者在同一国家历史文件中协同确保开局编制完整。[has_deployed_air_force_size](/wiki/trigger/has_deployed_air_force_size)：在事件或决议中可用此触发器检查空军规模是否达标，作为 set_air_oob 替换编制后的后续校验逻辑。[create_equipment_variant](/wiki/effect/create_equipment_variant)：为新 OOB 中出现的飞机型号预先创建对应的装备变体，避免 OOB 加载时找不到指定变体而报错。[add_equipment_to_stockpile](/wiki/effect/add_equipment_to_stockpile)：在 OOB 文件加载的同时向国家库存补充对应飞机装备，确保新编制的空军单位有足够装备可用。set_air_oob 的字符串值必须与 history/units/ 目录下的 .txt 文件名（不含扩展名）完全一致，包括大小写；哪怕多一个空格或字母大小写不同，游戏都会静默跳过该 OOB 文件，导致国家开局时没有任何空军单位且不报错，极难排查。Hands-on notes are AI-generated and checked against the vanilla command vocabulary — treat them as a starting point, not authoritative reference.

set_air_oob is primarily used to assign a dedicated air force order of battle file to a specific country within a mod. It is commonly employed when adding new historical starts, replacing default air force compositions, or allocating initial air units to custom nations. For example, when creating an enhanced French air force for a mod with a 1936 start date, you would add the following to that nation's history file:
# history/countries/FRA - France.txt
set_air_oob = "FRA_1936_Air_Enhanced"
The corresponding OOB file should be placed in the history/units/ directory, with the filename matching the string exactly.
[set_air_oob](/wiki/effect/set_air_oob) and [division_template](/wiki/effect/division_template): Air force OOB files typically require accompanying equipment and template definitions. Both work in concert within the same nation's history file to ensure a complete starting composition.[has_deployed_air_force_size](/wiki/trigger/has_deployed_air_force_size): This trigger can be used in events or decisions to verify whether air force size meets requirements, serving as a validation step after set_air_oob replaces the composition.[create_equipment_variant](/wiki/effect/create_equipment_variant): Preemptively create corresponding equipment variants for aircraft types appearing in the new OOB to prevent errors when the OOB loads and cannot find the specified variant.[add_equipment_to_stockpile](/wiki/effect/add_equipment_to_stockpile): Simultaneously add aircraft equipment to the nation's stockpile as the OOB file loads, ensuring the new air units have sufficient equipment available.set_air_oob must exactly match the .txt filename (without extension) in the history/units/ directory, including case sensitivity. Even a single extra space or incorrect case will cause the game to silently skip the OOB file, resulting in a country with no air units at game start and no error message, making this extremely difficult to diagnose.
