James Ironwood/Affiliation

Affiliation
Ironwood hails from the region of Atlas, where he is the headmaster of an academy, as well as a senior officer in the military, where he holds the rank of general. His military actively cooperates with the Schnee Dust Company to produce robotic soldiers.

In the Volume 2 Opening, Ironwood is also seen standing at the center of an unidentified faction, consisting of several Atlesian Knight-200s, a pair of Atlas Soldiers, as well as Penny and two other humans. These people may be students of his academy, part of Atlas' military, or something else entirely.

Ozpin
Ironwood has been shown and stated to be a very good friend of Ozpin, calling him by his nickname "Oz" and taking a familiar mode of speech with him. They speak rather freely to each other, and both can pick up on subtle cues from each other rather easily.

However, Ironwood is not afraid to question Ozpin's judgement, pointedly asking him if his "children" (the Hunters and Huntresses-in-training at Beacon Academy) would be capable of winning a war.

Ironwood said the the episode Field Trip that "I have served you faithfully for years." showing that they are not on even ground, and that Ironwood is somewhat subservient to Ozpin.

In the episode Breach, it is revealed that Ironwood has been sending the Vale Council what they describe as 'disturbing' reports about Ozpin's handling of Roman Torchwick's activities with the White Fang. As a consequence, he is made chief of security for the Vytal Festival. Whilst he is conciliatory in conversation with Ozpin, promising to protect their people to the best of his abilities, he later muses to himself that Ozpin brought what some might see as a humiliation upon himself.

Glynda Goodwitch
Glynda and Ironwood seem to have some past history, warmly greeting her when they meet. However, Glynda does not return this joviality, rather sternly saying "James" before promptly leaving Ozpin's quarters. Glynda also appears to disapprove of Ironwood's display of bringing airships to Beacon.

Ironwood is seen inviting Glynda to dance with him at the Beacon Dance. She reluctantly accepts, rolling her eyes when she takes his hand.

Qrow
Although it is unclear what their relationship is, Ironwood seems to be somewhat acquainted with Qrow.

Penny
Penny is seen standing uneasily with Ironwood's entourage in the Volume 2 Opening. In Painting the Town..., it is revealed that Ironwood assisted and sponsored Penny's father in her creation.

Ruby Rose
James seemed to have been grateful for Ruby for her matter in the recent incident at the Cross Continental Transmit Tower, believing her actions to be just and right, and said that she acted like a true huntress. Ruby herself seemed to be grateful for such comments.
