Asa (shields) are a crucial attribute of warriors and warrior chiefs, forming part of their ceremonial and battle attire as represented on the Emwin Arhe (royal treasures). Asa were usually made from elephant or crocodile skin and used by warriors for protection during hand-to-hand combat (Osadolor 2001, p. 102). Interestingly, the form of Asa depicted on historic royal artefacts differs from those found in museum collections today, reflecting changes in shield shapes and designs over time.

Ẹroro (bells) frequently appear as ornaments worn by figures depicted on the Emwin Arhe, particularly on Ama-Eronmwon (bronze relief plaques) and Aken’ni Elao (carved tusks). These Ẹroro are most commonly quadrangular in form or, less commonly, cylindrical with rounded tops. Quadrangular Ẹroro worn around the neck are often part of the attire that indicates that figures can be interpreted as warriors, alongside the Akọn Ẹkpẹn (leopard tooth neck ornament) and the Ohian Ẹkpẹn (leopard tunics).

Asoro (spears) were used as weapons in battle and for hunting ( ; Ọbazee 2025, p. 37). According to , there were two types: long and short. Figures holding Asoro are often depicted on Ama-Ẹrọnmwọn (bronze relief plaques), sometimes in battle scenes and at ceremonies and festivals.

The frequency with which Benin warriors are depicted in Emwin Arhe (royal treasures) reflects the importance of the army and military to the Kingdom, as well as the role of royal art as an archive in which artists from the palace guilds recorded important people, events, and institutions. The army was organised into a number of regiments, with soldiers grouped according to the weapons they used, including archers, swordsmen, crossbowmen, and spearmen ( ).

Warrior figures are frequently shown carrying weapons such as Asa (shields), Asoro (spears), warfare swords such as the Umozo or Ọhọ (executioners’ or warfare swords), Uhanbọ (bows), Ẹkpẹde (crossbows), and Ifẹnmwẹ (arrows), which were sometimes poisoned, as well as Osisi (firearms). Their dress also provides important indications of their military role. On both the Aken'ni Elao (carved tusks) and Ama-Ẹrọnmwọn (bronze relief plaques), warriors are depicted in a relatively standardised form, typically wearing an Ohian Ẹkpẹn (leopard tunic), Akọn Ẹkpen (leopard’s tooth neck ornament), an Ẹroro pendant around the neck, and the Uko ugbo-ohamwen (fortified chest band) ( ).

Differences are particularly apparent in the warriors’ headwear, both between individual figures and between representations on Aken'ni Elao and Ama-Ẹrọnmwọn. On the Ama - Eronmwon, the most common forms of headwear are crocodile-hide helmets and horsetail helmets with a front plate ( ). On the Aken'ni Elao, some warriors wear double-horned helmets ( ), while others wear simple rounded hats or helmets ( ). The most frequently represented warrior type on the tusks, however, wears a helmet with cowries sewn onto a front panel ( ).

Many different kinds of Ẹrhu (headwear) are worn by the various figures depicted in the imagery of Benin royal artefacts. Through comparisons with ceremonial regalia still worn by chiefs and members of the royal court, including the Ọba himself, some Ẹrhu have been used to identify the different figures depicted. For example, the conical hat worn by high-ranking town chiefs as part of the pangolin regalia, still worn at ceremonies, is also visible on figures on some Ama-Ẹrọnmwọn (bronze relief plaques) ( ). Other examples include the distinctive bell-shaped helmet associated with the Iyasẹ ( ). Figures who wear a shallow-brimmed hat and a cross have been identified as Ewua or Ohensa priests ( ).

Different kinds of helmets and headwear were worn by warriors, reflecting the many different ranks and roles in the army at any given time, as well as developing trends that were in turn represented on Emwin Arhe created at different points in time. Warrior figures wearing helmets covered in cowrie shells were carved on the Aken'ni Elao (carved tusks) (Blackmun 1984, p. 330), yet on the brass Ama, warriors are sometimes depicted wearing helmets made from crocodile hide or horsehair with a front plate (Osadolor in Plankensteiner 2007, cat. no. 238, p. 457). Helmets made from horsehair with a front plate are one of the more common types represented on the Ama-Ẹrọnmwọn, and the demand for black horse tails was noted by both Portuguese and British traders during the late 17th and 18th centuries (Osadolor in Plankensteiner 2007, cat. no. 238, p. 457). Other warriors depicted on Ama-Ẹrọnmwọn wear helmets with a rounded top, chinstrap, and sometimes also a feather tucked into the left side. These types of headwear are known as Ẹrhu Iyokuo.

Attire worn for battle also differed from that worn for ceremonial occasions, such as the pointed headwear worn in combination with an ornate leopard-head tunic by war chiefs. Depictions of figures wearing this attire on brass Ama-Ẹrọnmwọn (bronze relief plaques) have been interpreted as representing the war chiefs’ participation in the war-ritual Isiokuo festival (Osadolor in Plankensteiner 2007, cat. no. 238, p. 457).

Another distinctive form of headwear is that worn by figures identified as leopard hunters on the brass Ama-Ẹrọnmwọn (relief plaques). These large helmets cover almost all of the leopard hunters’ faces except for their noses, eyes, and upper lips, and are made of an unusual material that remains unidentifiable (Plankensteiner 2007, cat. nos. 68–69, p. 322).

European figures are also portrayed with distinctive hats, such as Portuguese three-cornered hats. These depictions reflect the artists’ keen observation and highlight the impact of European trade and military assistance (Ezra 1992).
