In the Star Realm, natural disasters can be divided into: ultraviolet-scorching sun, ocean tsunami, volcanic eruption, world-destroying storm, thunder, frozen sky, nebula burst, and meteor fall.

There is also the encroachment and confrontation of races in savage galaxies outside of federal jurisdiction.

Hence the need to build planetary defense weapons:

It is mainly in the form of satellites, that is, satellite fortifications.

Generally used for planetary defense, huge size, in order to reduce costs, generally used liquid substances frozen in space, no maneuverability, in low earth orbit, under the thick ice, frozen with a large number of artillery and missile launchers, can also carry a number of carrier-based aircraft.

Since the ice defense ability is comparable to armor, and can scatter the damage of energy weapons to a certain extent, it is very difficult to bite.

Ground warfare, is armed ground equipment:

Combat Mechs: Divided into light mechs, medium mechs, and heavy mechs.

1. Light mecha, human equipment.

The main tasks are: reconnaissance, search, rescue, maintenance of law and order in the occupied areas, etc.

2. Medium-sized mecha, 3-4 meters, human equipment.

The main task is to direct the robot in battle, as well as provide fire support to light mechs, etc.

3. Heavy mecha, human equipment.

The primary weapon is an energy weapon, and the secondary weapon is a kinetic weapon.

In order to enhance the awareness of disaster prevention and mitigation among all mankind, popularize and popularize the knowledge of disaster prevention and mitigation and the skills of disaster avoidance and self-rescue, so as to minimize the losses of natural disasters. Yuan Xingyao organized the members of the free group to explain the prevention and response knowledge of some common natural disasters, hoping that human beings can understand it and enhance their own disaster prevention resistance.

Since then, the Escape Regiment has set up a Chenxing Battalion-Disaster Shelter-Disaster Prevention Team.

The mission of the disaster prevention team is to minimize the damage caused by natural disasters.

As a result, the disaster prevention manual has been disseminated among the private sector.

How to deal with sudden floods - calmly observe and move quickly

(1) Calmly observe the water and topography, and then quickly move to nearby high ground and buildings.

(2) There are no high-rise buildings nearby to avoid, and buoyant items such as wooden basins, wooden chairs, etc. can be grasped. If necessary, you can climb a tall tree to take refuge.

(3) Remember not to climb onto the roofs of adobe houses, which are prone to collapse after being soaked in water.

How to avoid hail - don't forget to protect against lightning and lightning

(1) Close the doors and windows, and properly place outdoor items.

(2) Do not go out at will, and ensure that the elderly and children stay at home.

(3) If you are outdoors, do not take shelter from hail under the eaves of high-rise buildings, chimneys, telephone poles or large trees.

(4) While preventing hail, it is also necessary to be prepared for lightning protection.

How to avoid a typhoon - try to avoid walking by the river

(2) Try to avoid walking on rivers and bridges, as pedestrians are easily blown down or blown into the water on the road, bridge, or waterside, and are injured or drowned.

The earthquake is coming--send you the earthquake self-help formula

(1) The high-rise building is withdrawn, and the elevator cannot be taken.

(2) The bungalow is particular about shock absorption, whether it is to run or stay, to make decisions according to local conditions, and to miss the opportunity to rest. （

(3) The secondary disaster is harmful, and it is necessary to prevent it as much as possible, and the power gas is a hidden danger, and the gate should be closed in time during the earthquake.

(4) It is difficult to stand in a strong earthquake and bumps, so it is the most obvious to avoid the nearest place, and the small room under the table under the bed is waiting to be determined to ensure safety.

(5) During the earthquake, the fire is prone to occur, so lie on the ground and be calm, wet the towel and cover the mouth and nose, and bend over and crawl against the wind.

How to escape from a fire – soak your clothes and wrap yourself around

(1) Stay calm, quickly determine the danger and safety location, and evacuate as soon as possible.

If possible, use wet cloths, towels, etc. to block the doors and windows in the direction of the fire area, and continuously wet them with water, and at the same time close to the doors and windows of the side without fire to call for help. At night, you can use a flashlight and a white cloth to swing to send a distress signal, and you must not take the elevator or jump off the building.

Avoid lightning strikes – stay away from antennas, utility poles, lightning rods

(1) Lightning rods and their grounding wires away from buildings.

(2) Stay away from all kinds of antennas, telephone poles, towers, chimneys, flagpoles, if possible, should enter buildings with lightning protection facilities or metal-shelled cars and boats, but canvas caravans, tractors, motorcycles, etc. are more dangerous when thunderstorms occur, and should be kept away as soon as possible.

(6) Close the doors and windows to prevent spherical lightning from entering the room and causing harm; disconnect the outdoor antenna of the TV from the TV during a thunderstorm and connect it with the grounding wire; try to stop using electrical appliances and unplug the power plug; do not make phone calls and mobile phones; do not approach indoor metal equipment, do not approach damp walls.
