The following comes from James Turner's PALLAS ARMATA. Published 1683, but written in 1670/71 and taken from his earlier experiences during the tail-end of our period.

"In former times a Captain march'd in the head of his company with a Headpiece, a Corslet, and a Gorg, all High Proof. and so did the Lieutenant in the Reer. But you may now travel over many places of Christendom before you see many of those Captains and Lieutenants. The difference of the armour was none but that the Captain's helmet was decorated with a Plume of Feathers, the Lieutenants none. The Feathers you may peradventure yet find. but the Headpiece for the most part laid aside."

The Spanish & French captains and Lieutenants likewise carry pikes, the Spanish shoulder'd, the French Comported: The Germans, Swedes, Danes, and almost generally all others carry them in their hands but canes.; but indeed....Officers should have some other Offensive weapons in their hands other than Canes and Swords, and on the march their servants may carry these, whether they be Pikes or Partizans...'The Marquess of Guast, Alphonso Davalo. who had command of several Imperial Armies, when his master Charles the Fifth took a view of his numerous forces at Vienna, march'd in the Head of his Infantry with a Pike in his hand.

Marshal Monhue at the Battle of Ceresole carried a pike, because he led a great Batallion of pikes: but on all other occasions he used a Halbert or Partisan.... he tells us of the Halbert ...."I lov'd always to play with that batton".

The Serjeant if distinguished from the Captain and Lieutenant because he shoulders his Halbert, they comport theirs. And I suppose it were fit the Captains and Lieutenants, Halberts or Partizans should be diversified by several trimmings.."
