For $3.99 USD, at the Bronze Age, you would get 2 Stone Throwers, 2 Slingers, 2 Warriors, and 2 Bronze Age Champions.

If you really want to have all the Bronze Age Units available to you, usually there is a "Special Deal" offered by FoE called the "Army Pack". In fact, if possible, I would advise not even researching any other Bronze Age Unit until asked by a FoE Special Event to complete a Research, so at least you can be compensated for a useless Research. Generally, you spend so little time in the Bronze Age, that constructing the camps for any Bronze Age Unit, with the exception of the Spearfighters (the Bronze Age Light Infantry Unit) is really a waste of time and resources. The only exception to that mantra is the Bronze Age. I find that having a balanced force protecting my city gives me the best chance to defeat Looters when they come calling. My general philosophy is to build every unit available to me at my current level. Not only is the military necessary to defend your city against Looters, but also to conquer new Provinces, to take part in GvG Combat and Guild Expeditions (at Iron Age, or above), and to fulfill Advisor and Event Tasks.

One of the fundamental aspects of this game is establishing and maintaining a viable military force.
