hypaspist

As for term Hypaspist, it still lived on in the army.

Philip served as a royal Hypaspist in the service of Alexander with his brothers.

The Hypaspist and the armed grooms of the cavalry then attacked and eliminated these survivors.

Hearing this, Onesilus said to his hypaspist, a Carian of great renown in war and a valiant man...

A hypaspist would differ from a skeuophoros in most cases because the "shield bearer" is a free warrior and the "baggage carrier" was probably usually a slave.

For instance, a Hypaspist was sent by Philip V to Larissa to burn state papers after the defeat at Cynoscephalae.

The hypaspist has a large Hoplon type shield, a different sword scabbard and no crests on his helmet, whereas the phalangite has a too small round shield supplied.

Polybius mentions a hypaspist being sent by Philip V of Macedon, after his defeat at the Battle of Cynoscephalae in 197 BC, to Larisa to burn state papers.

The actual fighting unit of hypaspists seems to have lived on in Macedonia as the corps of 'Peltasts', whose status, equipment and role seems to have been almost exactly the same as that of the hypaspist under Philip.
