One Fort - One Unit

[Vindex]

A Forward Operating Base implies a rear one...as indeed FOBs have. Where is the Roman parallel here?

In simplistic terms my answer would have to be - the legionary fortress.

But are not the forts you are discussing here meant to sustain a force over a period of time MUCH longer than the "equivalent" FOB (and I wont mention air drops... :wink: )? Sources and discussions elsewhere indicate that store houses in these forts were suppossed to sustain it's occupation force for up to a year.

And one could argue that a FOB in Afghanistan is not really what a FOB is about...far more permanent and more greatly defended than the quick, agile base they used to be. Strategically, when does a dug in company position become/grow into a FOB I wonder? (but WAAAAY off topic!)
