Solid bastions are those that are filled up entirely and have the ground even with the height of the rampart, without any empty space towards the centre. [7] Void or hollow bastions are those that have a rampart, or parapet, only around their flanks and faces, so that a void space is left towards the centre. The ground is so low, that if the ...

A bastion fort or trace italienne (a phrase derived from non-standard French, meaning 'Italian outline') is a fortification in a style developed during the early modern period in response to the ascendancy of gunpowder weapons such as cannon, which rendered earlier medieval approaches to fortification obsolete.
The fort is rectangular, featuring two small bastions and two semi-bastions. The section of the defensive wall connecting the two northern bastions is protected by a ravelin. The southern semi-bastions are linked by an embrasured gorge, a narrowing in the triangular portion of the ravelin where it meets the defensive wall. [76] [77]

It is positioned to be the last line of defence, should the enemy breach the other components of the fortification system.
Chinese naval bastions are far more crowded than Soviet ones. There is a lot of commercial traffic in the South China, East China, and Yellow Sea (by contrast, the Soviet bastion of Sea of Okhotsk and the Kara Sea were isolated). [4] This makes it easier for the Chinese to hide their submarines in these waters.
