Reading notes

Ad Familiares 7.8 §1 the perquisites of the tribunate
Tribunatus commoda: the pay, prestige, and prospects of a military tribunate, a staff post Caesar had evidently offered Trebatius. Cicero is amazed Trebatius would slight it, the more so since (the next clause notes) it carried none of the hard labour of campaigning.
Ad Familiares 13.12 §1 military tribune
Tribunus militum: a senior officer of a Roman legion (six per legion), often the staff posting given to young men of equestrian standing on a governor's command. Q. Fufidius held this rank under Cicero in Cilicia in 51-50 BC.
Ad Quintum Fratrem 2.12 §3 He is a military tribune in your army
The tribunus militum was a senior officer of a legion, six to a legion; Orfius held this rank in Caesar's Gallic army, where Quintus was serving as a legate.
