I have set up hoplite armies in the passes of Greece to fend off the Brutii and Macedonians, but they are usually attrition wars, not war-winners.

I have also used hoplite walls in sieges in the city of Tarentum to bleed the Romans dry in RTR while I fight my main abttles against the Thracians and Carthaginians, again mainly attrition not generally war-winners.
