Latin phrase for Roman Army?

[Renatus]

Nathan Ross wrote that

Simon James, In Rome and the Sword, makes an interesting point: "Startlingly, the Romans had no term equivalent to our phrase 'the Roman Army', because no such entity or concept existed."

and I made the point that this was not strictly true, as Tacitus had used the phrase exercitus Romanus, even if the Roman army themselves did not. I think Tacitus counts as a Roman ;-)

I hope that makes things clearer.

Strangely enough, I understood that. It was your reaction to my post concerning the circumstances in which Tacitus used the expression that puzzled me.
