Gaiaterra: Elysea's Conflict/Tier system

In Gaiaterra: Elysea's Conflict, advance infantry, vehicles, upgrades, and so on are locked behind a tier system, requiring the commander to invest resources to unlock their stronger armaments, though how is different per factions. Every faction has only 5 tiers and tech levels. Each faction's headquarters initially set their alert status to Tier I.

Tiering up
There are a total of five tiers each factions have and a different method each of them have to access advanced units, structures, or upgrades, depending on their type.

In order get to the next tier, mainly Tier IV and V, the player must usually get to the 3-star and 5-star General's Promotion, however getting the next tier after getting the certain General's Promotion rank is depends on what faction is on, for example, Aquila would had to set their DEFCON levels to 3, 2 and 1 that can be purchased on the Command Center, while Voshkod requires to build a Tier acess building (i.e Battle Lab) to advance.
