Batavians: an offshoot of the Germanic Chatti, who fled after a period of civil war, the Batavians settled on what the Romans called the Rhine island in modern Holland.

centurio regionarius: a post attested in the Vindolanda tablets, as well as elsewhere in Britain and other provinces. They appear to have been officers on detached service placed in control of an area. A large body of evidence from Egypt shows them dealing with criminal investigations as well as military and administrative tasks.
centurion: a grade of officer rather than a specific rank, each legion had some sixty centurions, while each auxiliary cohort had between six and ten.

Auxiliaries were either formed in milliary cohorts of 800 or more often quingeniary cohorts of 480. Cohortes equitatae or mixed cohorts added 240 and 120 horsemen respectively. These troopers were paid less and given less expensive mounts than the cavalry of the alae.

legion: originally the levy of the entire Roman people summoned to war, legion or legio became the name for the most important unit in the army.

In ad 98 there were twenty-eight legions, but the total was soon raised to thirty.

omnes ad stercus: a duty roster of the first century ad from a century of a legion stationed in Egypt has some soldiers assigned ad stercus, literally to the dung or shit. This probably meant a fatigue party cleaning the latrines – or just possibly mucking out the stables. From this I have invented omnes ad stercus as ‘everyone to the latrines’ or ‘we’re all in the shit’.
optio: the second in command of a century of eighty men and deputy to a centurion.
phalerae: disc-shaped medals worn on a harness over a man’s body armour.
pilum: the heavy javelin carried by Roman legionaries. It was about 6 to 7 feet long. The shaft was wooden, topped by a slim iron shank ending in a pyramid-shaped point (much like the bodkin arrow used by longbowmen). The shank was not meant to bend. Instead the aim was to concentrate all of the weapon’s considerable weight behind the head so that it would punch through armour or shield. If it hit a shield, the head would go through, and the long iron shank gave it the reach to continue and strike the man behind. Its effective range was probably some 15 to 16 yards.
posca: cheap wine popular with soldiers and slaves.
praetorium: the house of the commanding officer in a Roman fort.
prefect: the commander of most auxiliary units was called a prefect (although a few unit COs held the title tribune). These were equestrians, who first commanded a cohort of auxiliary infantry, then served as equestrian tribune in a legion, before going on to command a cavalry ala.

princeps: a Roman emperor was called the princeps or first citizen/first servant of the state.

scorpion (scorpio): a light torsion catapult or ballista with a superficial resemblance to a large crossbow.

signifer: a standard-bearer, specifically one carrying a century’s standard or signum (pl. signa).
Silures: a tribe or people occupying what is now South Wales. They fought a long campaign before being overrun by the Romans. Tacitus described them as having curly hair and darker hair or complexions than other Britons, and suggested that they looked more like Spaniards (although since he misunderstood the geography of Britain he also believed that their homeland was closer to Spain than Gaul).
singulares: the legate of a province had a picked bodyguard formed of auxiliary soldiers seconded from their units.
spatha: another Latin term for sword, which it is now conventional to employ for the longer blades used mainly by horsemen in this period.
speculator: a soldier tasked with scouting.
tesserarius: the third in command of a century after the optio and signifier. The title originally came from their responsibility for overseeing sentries. The watchword for each night was written on a tessera or tablet.

tiro (pl. tirones): a new recruit to the army.
tribune: each legion had six tribunes. The most senior was the broad-stripe tribune (tribunus laticlavius), who was a young aristocrat at an early stage of a senatorial career. Such men were usually in their late teens or very early twenties. There were also five narrow-stripe or junior tribunes (tribuni angusticlavii).
triclinia: the three-sided couches employed at Roman meals.
tubicen: a straight trumpet.
Tungrians: a tribe from the Rhineland. Many Tungrians were recruited into the army. By ad 98 a unit with the title of Tungrians was likely to include many men from other ethnic backgrounds, including Britons. In most cases, the Roman army drew recruits from the closest and most convenient source. The Batavians at this period may have been an exception to this.
turma: a troop of Roman cavalry, usually with a theoretical strength of 30 or 32.
valetudinarium: a military hospital.
venator (pl. venatores): a type of gladiator who specialised in fighting animals in the arena.
