On BuildingTypes

By constructing the building, the house's "technology level" is increased to this value, if necessary.

On Infantry/Vehicle/Aircraft Types

This flag specifies the "technology level" necessary to build this object.

In [MultiplayerDialogSettings]

This flag specifies the maximum TechLevel achievable in the game. In previous games, you could control this by means of another slider, like the one used for Starting Money or Game Speed. The effect of this limit is that only TechLevel values in the interval 0 - this value (inclusive) are considered "allowed", and all others are disabled.

On Houses

This flag specifies the starting tech level for this AI-controlled house.

Limitations of this system

TechLevel limitations

TechLevel	Can be
	Built by AI	Built by Humans	A Crate goodie	A Secret Lab boon
-1
0 through the maximum (set in MultiplayerDialogSettings)
above the maximum

TechLevel -2 and below are considered as buildable at any TechLevel.

And AI doesn't build Techlevel -1 units even if given in TaskForces. Buildings case is covered in the table above.

Additional note

The hack that Westwood used to make battle bunkers in YR stay owned when empty and not evict infantry when damaged is tied to Techlevel= ; if the techlevel is -1, the building will be treated as a normal civilian building. If the techlevel is anything besides -1, it will be treated with battle bunker logic

Bugs/Side-Effects/Unexpected Limitations
