It is not possible to determine whether kills or deaths occurred before or after equipping the loadout. All kills or deaths of a player are attributed to the loadout or loadouts that the player used in the game. Attachment combination data is less reliable for less popular weapons. However, when aggregated on a global scale of all matches analysed by WZ Ranked it is possible to determine the most popular loadouts in Warzone with a pretty high accuracy. Therefore, it is not possible to analyse loadouts for each individual player.
Only about 2%-6% of data of all loadouts used in a game is retrievable from COD API. It is not possible to retrieve each loadout used by every player in every game from COD API.
