SYNTAX
[##:##] Command : upgrade   The upgrade command allows a country to set the tech level of its ships/land units/planes to the country's current tech level.

Each ship/land unit/plane to be upgraded must be at least 60% efficient and be in one of the country's harbors/headquarters/airports that is at least 60% efficient.

Upgrading costs 15% of the full build cost in money and avail, and reduces the efficiency of the ship/land unit/plane by 35%. Repairing these 35% will then consume work and resources as usual.
