A random drop is an item reward given at the end of Online Co-Op Missions or Team Deathmatch in Ace Combat Infinity. Each player has a chance to receive special aircraft, emblems, skins, contracts, research reports, Stocked Fuel, Special Supply Tickets, and certain amounts of credits.
First Flight Bonus
The First Flight Bonus is a special random drop that only occurs during the first 10 days of a player joining the game.
The first time a player enters the game and plays a match in Online Co-Op Missions, they will receive one of the rewards below. This counts as Day 1. A player will receive their Day 2 reward when they play at least one match at least 24 hours after receiving the Day 1 reward, and then receive the Day 3 reward after one match at least 24 hours after receiving the Day 2 reward, and so on. Among bonus credits and fuel, players can earn the Rapier, Javelin, Saber, and Quad Cross emblems and an Aircraft Research Report.
Each item can only be awarded once, on the day it is assigned to the player. None of these items will be given as a duplicate.

Limited-Time Drop
In addition to common drops, Infinity hosts a limited-time drop system. These are a second drop awarded alongside the first random drop, inside a special red container/gold container (whereas the first drop is a silver container). These award bonus credits, Stocked Fuel, various research reports, and contracts; while a special gold container replaced the special red container, containing limited-time items such as 3x Stocked Fuel, huge credits, skins, Special Supply Tickets, monthly special aircraft, or Collaboration Event emblems/special aircraft.
Since Update 2.00, players can recognize if they obtain a special aircraft drop by watching cutscene of a cloaked aircraft that parks in the hangar.
