So I had my first full playthrough of Elemental since release and enjoyed the game except for some minor bugs and UI issues that are already being addressed in the forums. (Not being able to view city stats during leveling up is a major irritant). One thing I couldn't find, so here goes:

Is it possible to improve and upgrade military assets already built as better armor and weapons are researched? Or am I pretty much better off using them as canon fodder? If not, it is a shame to lose their relative gains in experience and level. If so, how? I couldn't figure it out.

[Edit] And before you flame me for not using search you should know it wasn't working for this forum.
