I'd forgotten this thread :embarrassed:

PickledGecko, thank you. That is not quite the feature I was speaking of, perhaps quite similar but not so user friendly. Fortunately the 1.2 patch has restored the old system where you simply hold down 'alt' while giving a movement order. This works with all units, including single ungrouped ones.

jullii caesar, the testudo formation in in the game. It is useable by all types of Roman legionaries, i.e. the units Rome gets after the Marian reforms. I think some of the factions with imitation legionaries, such as the Seleucids, can also use testudo with their copycat legionaries.

New units are gained in two ways:
1. Building a better barracks/stables/archery range. As each city grows you have access to better buildings in that city; when you upgrade one of the three troop producing buildings you gain access to better units and well as the original ones you had before.
2. The Marian reforms. This only affects the four Roman factions. It is based on a historical event and person, and 1.2 has altered the trigger quite a bit. Suffice it to say when the Romans have at least one very advanced city and it is past a certain date (220BC I think it it supposed to be now) then the Romans will get a whole new army system. Their old units, like the hastati and triarii, will become obsolete and you can't build or train them any more. Instead you have access to the new Roman legionary and their supporting units.
