Greek unit names?

[keravnos]

So what do "phalangitai deuteroi, pantadapoi, and pheraspidai" mean? Obviously the two former and machimoi are meant to represent lower class members of the phalanx, but what exactly do these names mean?

Also what does "pheraspidai" mean? I understand is has something to do with shields, especially as it is meant to represent one form of the hypaspists. But, my greek knowledge being close to minimal, I don't know what it actually means together.

Thanks in advance!

Phalangitai deuteroi = Second (class) phallangites
Pantodapoi= From all places literally "born anywhere"
Pheraspidai= Those who carry aspis shield, and yes it should be pheraspides.
