Forts, bunkers, and coastal defenses of the Republic.

The hilly terrain of the Republic suits itself incredibly well for defensive manouvers, as the Republic itself would learn on the multiple wars that would take place in what now makes the country, however, one cannot simply count on the terrain to do the job, the building of forts and bunkers, and ocassionally improvised defenses is considered an art, and the armed forces of the Republic have certainly taken this lesson to heart.

The first example many would see when entering the Republic is the coastal defences of the ports of the Republic, and as naval strategy sustains, it cannot be assumed that the fleet will be present to provide support against an invading enemy, as massive usage of artillery allows for the coastal forts to be plentiful and well mantained, thus, this two realities shape how the coastal defenses have been built.
The main shape they take is that of a triangular shape made to face the sea, this will be inclined at such a way as to both allow a person to stand on top of it, and for a person to be unable to climb it when in front of it.
These constructions, while originally made of stone, have now switched to using concrete. These constructions will be connected to each other through an underground path, and from there, there will be stairs that connect the top floor of the construction with the inside.
The battery is placed on top of the construction, and ammunition along with mantainance equipment is placed on the inside of the construction.
The construction has 2 slots on the part facing the sea, these slots are large enough to fit a standard firearm.
The underground tunnels that connect to the constructions are vulnerable if an enemy jumps in from the construction, so they are made in a way as force chokepoints where firepower from small arms can be let through freely. And cover is built into the sides of the walls to prepare ambushes.
Explosives can be used to collapse the tunnels if the situation calls for it.
A building is used to connect the surface with the constructions by the tunnels, the building is on the city, and houses ammunition and garrisons.
The buildings on the surface will be near the coast, and connect with multiple constructions
A construction connected to a building in the surface will only be able to connect to that building, as to force chokepoints.
All military constructions take priority over civil constructions, these means that the military has some say in how the port is built, and will kick out civilians who wish to build on a section they called for.
This also means that civilian constructions had to obey certain military requirements for building, and the city has multiple locations that serve as killzones and bunkers if any invaders land.
On the coast, ramparts are built and the constructions will be painted with colors made to hide their position.
Bunker personnel is assigned their turns weekly, and they are under the administration of naval command.
While ideas for mass usage of explosives on the port to deprive it from the enemy exist, they have been shelved, as it is most certainly an insane thing to do.
More experimental ideas on coastal defense exist, such as floating batteries on the water or mines, but have proved unfeasible due to various constrains.
The two places where these fortifications are most used would be the important ports of the Republic, but smaller fortifications exist on river mouths and less patrolled places.

Inland fortifications take a different shape to satisfy the needs of the military, as all military enemies have been dealt with for much time, a large aount of fortifications have fallen to disuse and lack of mantainance, still, so as to keep up with the old nickname of the nation, "The Fortress Republic" the military has plans to reactivate, test out, and rebuild the forts for when a new enemy appears in a nearby nation. In the modern era, the reinassance of Hoshiyomia has stirred some in the military to proceed with early cautions for the plan.
The main area of the abandoned forts is located near the western border with Hoshiyomia, as a result of the multiple wars that happened in this zone from multiple emerging countries in the area. They eventually fell to the Republic, but they remain very outdated.
The most modern forts in the Republic are the those that employ steel and concrete, and developments on industrial production have made these relatively easy to build for the Army.
Border forts will generally be built into the ground, larger fortifications inside the country, with smaller bunkers connecting to it proliferating closer to the border, the idea being to bog down the enemy to permit for easier counter strikes by local military units.
The larger constructions made to hold the area are built as Star Forts, althought newer tests and a call to modernize the forts have seen them being replaced with what is called Polygonal Forts, while less visually impressive, have proven to be better against the potential firepower from the enemy, while maximizing that of the fort.
The first forts to be updated are those of the Hoshiyomian border, with the druid forest and the monk mountains being set to be updated later as they lack the mass usage of artillery and firepower that the more modern states have.
Forts on the border of the druids have certain key differences, those being made to resist any potential rading force that settles inside the forest, and a higher quantity of lead material to fight off the hazardous effect of the forest, as the many tribes of the forest have shifting loyalties, and there being no central force to organize them, it's been possible for bunkers to be set further inside their territory by playing diplomacy with them and taking zones that are only claimed by the more nomadic groups of people. Thus, these bunkers are specifically prepared against more flexible forces.

City forts differ from the more standard border fort design by the cities outright being designed as forts.
Multiple civilian buildings took to using military designs and make them into a more livable space, killzones and chokepoints are designed into the city proper, and efforts into making the cities more difficult to take by a military force have been put into the school of architecture of the University.

Most army forts are organized to have local civilians use them, and trained into them, and great effort has been put into standarization so that a civilian from any part of the Republic can take place and work in any fort of the Republic.
This also means that professional units are trained into fort usage, but they will not be the main garrison of one of them.
