Ironwood took great pride in his role as a protector of Atlas and believed the Kingdom had the responsibility to protect Remnant. As a result, he often employed shows of force as a way of projecting a sense of strength and safety he felt was necessary to ward off enemies.

However, as courteous as Ironwood appeared, he could also be incredibly blunt and bullheaded, often preferring the direct and brazen approach. When he felt necessary, Ironwood was not afraid to bring the full might of his military command to bear, which sparked disagreements with both Glynda and Ozpin. Nevertheless, Ironwood was extremely loyal to his comrades, and however questionable his methods were, he seemed to have genuinely good intentions behind them.
For all his good intentions, he did have a number of flaws. Ironwood consistently believed only his ideas were justified, something he did not deny. This lead to a more proactive yet headstrong approach to problems and attempting more strict preemptive measures, as opposed to Ozpin's more subtle, reactive and analytical methods. Ironwood also didn't care about Ozpin's rules and ideology which was shown when he created the Ace Operatives, a five person team that lacked a individualistic color theme because he preferred an efficient collective team instead.

Voicewise I would like something similar to Jason Rose's take on the character
