Literally meaning ‘banner’, a bandon typically consisted of between two hundred and four hundred men, usually skutatoi, who would line up in a square formation, presenting spears to their enemy from their front ranks and hurling rhiptaria from the ranks behind.

Chi-Rho: The Chi-Rho is one of the earliest forms of Christogram, and was used in the early Christian Roman Empire through to the Byzantine high period as a symbol of piety and empire.

Tagma skutatoi may well all have been afforded iron lamellar armour.
Skutum: The Byzantine infantry shield that gives the skutatoi their name. Usually kite or teardrop-shaped and painted identically within a bandon.
Spathion: The Byzantine infantry sword, derived from the Roman spatha. Up to a metre long, this straight blade was primarily for stabbing, but allowed slashing and hacking as well.
Strategos (pl. Strategoi): The themata armies of Byzantium were organised and led by such a man. The strategos was also responsible for governance of his thema.
Tagma (pl. Tagmata): The tagmata were the professional standing armies of the Byzantine Empire. They were traditionally clustered around Constantinople. These armies were formed to provide a central reserve, to meet enemy encroachment that could not be dealt with by the themata, and also to cow the potentially revolutionary power of those regional armies. They were well armoured, armed, paid and fed. Each tagma held several thousand men and was composed exclusively of cavalry or infantry. In the 11th century AD, some of these tagmata were moved closer to the borders to deal with emerging threats. In addition, a raft of smaller, ‘mercenary’ tagmata were formed in these regions, comprising largely of Rus, Normans and Franks.
Thema (pl. Themata): In the 7th century AD, as a result of the crisis caused by the Muslim conquests, the Byzantine military and administrative system was reformed: the old late Roman division between military and civil administration was abandoned, and the remains of the Eastern Roman Empire’s field armies were settled in great districts, the themata, that were named after those armies. The men of the themata would work their state-leased military lands in times of peace and then don their armour and weapons when summoned by the strategos to defend their thema or to set out on campaign alone or with the tagmata. The manpower of each thema varied vastly, with some able to field only a few thousand men while others could muster as many as ten or fifteen thousand men. The diagram at the front of the book depicts the structure these forces would be organised into. In the 11th century, the thematic system was in steep decline, with the tagmata gradually taking over as defenders of the borderlands.

Toxotes (pl. Toxotai): The Byzantine archer, lightly armoured with a felt jacket and armed with a composite bow and a dagger.

*The use of a sash to denote rank is backed up by historical texts, but the sash colours stated are speculative.
