- Alteration: Increase protection or decrease encumbrance of some bronze armors.
- Effects: Increase mobility and defense, or protection, of some units.
-	   Myrmidons get AP closer to other heavy infantry.
- Rationale: Various copper alloys may be classified as bronze, and they have varying hardness and density characteristics.
-	     All of the alloys with a reasonable amount of tin are denser than unalloyed iron - but only by about 8% to 10%.
-	     While bronze should receive some additional encumbrance penalty, it should not be excessive as in the case of the 
-	     Bronze Hauberk and Hoplite Helmet.
-	     At around 12% tin, bronze is harder than unalloyed iron. This should be reflected in better protection than equivalent 
-	     iron armors.

- TODO: Determine whether the rcost is reasonable. Bronze items are founded/casted and require gathering two different metals.
-	Iron items are casted or forged and require gathering only one kind of metal. Start founding versus forging thread?
-	How much does gathering raw materials reflect on rcost, if at all?
- Bronze Cap
- - Protection: 17 (14)
-   Compare to Iron Cap.
- Hoplite Helmet
- - Encumbrance: 0 (1)
-   Compare to Full Helmet or Legionary Bronze Helmet.
- Bronze Cuirass
- - Protection: 15 (14)
-   Compare to other cuirasses.
- Bronze Hauberk
- - Protection: 18 (17)
-   Compare to other hauberks.
- - Encumbrance: 4 (5)
-   Compare encumbrance of Plate Hauberk to other, weaker hauberks.
- Bronze Scale Cuirass
- - Make equivalent to Scale Mail Cuirass.
- - Protection: 10 (9)
- - Resource Cost: 6 (5)
- Bronze Scale Hauberk
- - Make equivalent to Scale Mail Hauberk.
- - Protection: 12 (11)
- - Resource Cost: 9 (8)
