The delineation between Bullet Club members has become clearer now that Taiji Ishimori’s joined the War Dogs

War Dogs: These are the members who are based primarily in Japan. They may interact with members from other sub-groups but place more importance amongst themselves. They are typically characterised by their aggressive in-ring (or sometimes out of ring) wrestling style along with classic Bullet Club tactics

Bullet Club (unaffiliated): These are members who are not based in Japan (and not primarily based in Australia or New Zealand) and appear infrequently on the New Japan main product. When they do appear they may partner amongst themselves or bolster the numbers of other sub-groups

Rogue Army: These members are primarily based in Australia and New Zealand on New Japan Tamashii. This faction typically does not appear as a whole on the New Japan main product so when members do appear they affiliate themselves with other sub-groups for the time being

House of Torture: These members are very insular and rarely interact with members of other sub-groups. In fact they often antagonise other members of Bullet Club. Despite this they're connected to the other sub-groups by a shared history and both them and the rest of Bullet Club seem not to regard them as an entirely separate unit. Their matches are characterised by outside interference and attempts to gain advantages through illegal tactics out of view of the referee
