Here's a summary of all Fireteams available in Operations Subsection. Note that notation here is different from usual, but it allows and disallows all the allowed combinations. Hence, to check if Fireteam is valid, pick the one from the list and check that members fall within specified numbers. Do not use the "join"/"replace"/"count as" from normal Fireteam listing; these are already accounted for by allowed member numbers. REMEMBER: there is minimum and maximum number of members per Fireteam type some Fireteams have more restrictions, so for example Haris Fireteams D and E require all 3 members or they cannot be created at least one member of Fireteam: Haris/Duo must have the Fireteam: Haris/Duo skill in their profile/loadout it does not matter which member has the skill, so long as at least 1 member has it there is no such requirement for Fireteam: Core, as there is no Fireteam: Core skill despite Army apps showing "Fireteam: Core" in Skills section. This is done purely as a reminder for players. there is always a limit of active Fireteam types per army: 1 active Fireteam: Core, 1 active Fireteam: Haris you may have any number of Fireteam: Duo Fireteam: Core - minimum 2, maximum 5 members Core A: 0-5 Dakini, 0-2 Deva without Devabot, 0-1 CSU, 0-1 Samekh FTO Core B: 1-5 Deva without Devabot, 0-1 Samekh FTO Core C: 0-5 Yadu, 0-1 Rudra, 0-1 Samekh FTO, 0-1 Shakti Fireteam: Haris - minimum 2, maximum 3 members, including at least 1 member with Fireteam: Haris skill Haris A: 1-3 Asura, 0-1 Samekh FTO Haris B: 1-3 Deva without Devabot, 0-1 Samekh FTO Haris C: 0-3 Yadu, 0-1 Rudra, 0-1 Samekh FTO, 0-1 Shakti Haris D: 1-2 Deva without Devabot, 1 Asura, 0-1 Samekh FTO this Fireteam may only be created wilth 3 MEMBERS Haris E: 0-2 Yadu, 0-1 Rudra, 0-1 Samekh FTO, 0-1 Shakti, 1 Deva without Devabot OR 1 Asura this Fireteam may only be created wilth 3 MEMBERS Fireteam Duo : 2 members, including at least 1 with Fireteam: Duo.
