Mark 15:16

And the soldiers led him away within the court, which is the Praetorium; and they call together the whole band.

THE MOCKERY

The mockery about to begin was not the only mockery of Jesus, there being in fact no less than six, as pointed out by Major:

The Evangelists record six mockings of Jesus by: (1) the High Priest's servants; (2) Herod Antipas and his soldiers; (3) the soldiers of the Roman garrison; (4) the general public; (5) priests and scribes; and (6) the two crucified brigands.[7]

The Praetorium ... was the name of the area where soldiers were quartered at Caesar's official residence, or, as here, at the residence of any of Caesar's representatives. In this case, the reference is either to the tower of Antonio or to the old Hasmonean palace of Herod.

Called together the whole band ... The type of sadistic sport engaged in by soldiers of the imperial army was as brutal and detestable as anything that can be imagined. Turlington thought the group here was the Second Italian Cohort, but their military identity is not important. The Roman war machine was constantly engaged in bloody conflict in one part of the empire or another; and the dehumanization of the soldiery was an inevitable result. Notwithstanding this, the army was the last stronghold of the virtues which had held together the sprawling empire, and this accounts for the repeated favorable mention of centurions. See under Mark 15:39.
