Also known as self-propelled howitzer, is a howitzer mounted on the chassis of a tank with armored protection and self-propelled artillery system. Equipped with large-caliber howitzers, it can launch a variety of ammunition such as high-explosive bombs, armor-torn bombs, and incendiary bombs to adapt to different combat environments. It combines the mobility of tanks and the firepower of artillery, capable of rapid deployment and transfer on the battlefield. With a certain degree of armor protection, able to survive and fight in complex environments. It can not only provide fire support in war, but also play a role in non-war military operations. With its powerful firepower, good mobility and protection ability, it plays an important role in the modern battlefield.

It is an intercontinental ballistic missile displayed by North Korea and debuted at a military parade in October 2020, the 75th anniversary of the founding of the Workers' Party of Korea. Carried by an 11-axis transport vertical launch vehicle, the size and configuration of this large missile indicate that North Korea has the ability to manufacture such vehicles, which has previously been a factor in limiting North Korea's ICBM power by preventing foreign-made TEL procurement. The first flight test took place on March 24, 2022, and North Korea announced that it had successfully tested the missile. The development of such missiles is seen as the core strike means of North Korea's self-reliance and nuclear deterrent.

It is the key equipment used to launch, guide and control missiles in modern military equipment. It usually consists of the following parts: power system, guidance and control system, communication system and warhead system. Material selection is key to ensuring system performance and reliability, and commonly used materials include high-strength alloy steels, titanium alloys, and composite materials that require a balance between multiple requirements for strength, durability, corrosion resistance, and weight. The advantages include high-precision strike capabilities, long-range strikes, rapid response and deployment capabilities, as well as high-speed flight and complex flight trajectories, making it difficult for enemy defense systems to intercept.

It is a Chinese-made main battle tank, based on the Soviet T-54A tank design. It was first produced in 1958, served in 1959, started mass production in 1963, and stopped production in 1980, producing about 9500 vehicles. It was the main equipment of the Chinese People's Liberation Army until the early 21st century. During the service, it underwent many improvements, including the replacement of the 100mm smoothbore gun with a 105mm rifling gun, which became the cornerstone of subsequent Chinese tank designs. It has a traditional post-war layout with a battle bay at the front, an engine bay at the rear, and a cast dome-shaped turret at the center.

MK2-PFU is a sci-fi Combat Flamethrower, a weapon of science fiction. Adopting advanced flame spraying technology, it can generate high-temperature and high-pressure flames. Using a special mixture of fuel and gas, the flame is projected in the form of a jet through an injection device. The design emphasizes combat use, with strong killing power and range. It can spray flames several meters long, forming an instant flame wall that can inflict fatal damage on enemies and armored targets. It has certain protective measures, including fireproof coating and heat dissipation system. Equipped with a portable fuel supply system.
