Tactical vest is a kind of individual combat equipment that can integrate and wear most of the equipment required for personal combat, so as to facilitate the quick access to various equipment in the fight. In recent years, due to the influence of movies and media reports, a large number of survival game players have gradually changed their equipment for survival games from military products used by the military to special equipment used by the police or special military units. Among them, the tactical vest is one of the special service equipment. Almost every player who is engaged in survival games will prepare a tactical vest as one of his equipment.

Tactical vests can be roughly divided into the following categories:
1. ASSAULT:
In operations, they usually carry large reserve ammunition, grenades (fragments, smoke, shock, flash bombs, etc.), tools (door breaking, dropping, blasting, etc.), radios, short barrel shotguns, personal first aid supplies, etc., and necessities for CQB (CLOSEQUARTERBATTLE, indoor close combat) or CT (COUNTERTERRORIST, anti-terrorism) missions. The above equipment is required to be easy to carry and quickly access in action, so as to cope with sudden situations and achieve the best attack effect. This type of tactical vest is also the most commonly used tactical vest by the majority of survival game players, which is generally divided into two categories: military and police.

2. Sniper:
Snipers of general police or military special service units may sometimes perform long-distance sniping tasks, such as the two snipers described in the Fire Fighter film. It is necessary to carry a certain amount of ammunition (with the possibility of contacting the enemy), record books, long-distance video recorders (for surveillance and video recording), video communication equipment (which can transmit the captured images to the command post), dry food, water, first-aid supplies, etc. In addition, the special forces carrying out long-distance reconnaissance missions will also carry small global positioning system (GPS), satellite communication equipment and other special equipment. EAGLE is a tactical vest specially designed for DELTA FORCE.
3. MEDIC:
When performing a task, if ordinary medical personnel cannot effectively rescue the injured immediately, the team needs one or more members who have received emergency medical training. Give immediate medical treatment to the injured and stabilize the injured until the general medical staff can give proper first aid. The items carried are mainly weapons, equipment and a large number of first-aid supplies required by individuals to perform tasks. For example, Stallone played the role of the captain of the rescue team in the film "One Hundred Thousand Urgents" and wore a tactical vest specially designed for emergency rescue by the American (EAGLE) company when he was performing his mission.
4. ANTIRIOT:
The special ammunition required for riot suppression is usually larger than the general ammunition, such as tear gas, which is used to disperse the mobs. In addition, you need to carry a fire extinguisher to prevent the attack of gasoline bombs, tape or straps, and handcuffs. Some of the above items are used by secret service units in real operations, and are less likely to be used in survival games.

After you know your own use, you should understand the basic structure of the tactical vest, and then choose a better product. The tactical vest is mainly composed of cloth, equipment bag, buckle and sewing thread. Prerequisites for selecting fabrics are: non combustion supporting, durable, waterproof, etc. Early vests were mostly made of leather, canvas and other materials. However, because this kind of material can absorb water, it will increase weight because the vest absorbs water in rainy days or when performing amphibious tasks. Later, nylon was used as the material of vest, which not only reduced the weight but also increased its durability.
Nylon is divided into rough surface and smooth surface. Generally speaking, the tactical vest made of smooth surface nylon is more expensive than rough surface. Why?
Because the vest made of rough nylon is easy to generate static electricity, it will attract fire tongues during blasting (especially indoors), which is very dangerous! In terms of equipment bags and sewing threads, they should be fireproof, durable and corrosion resistant.
The equipment bag itself is slightly divided into thin and thick, and the tension is of course thick and high. The size of the equipment bag also determines the size of the equipment you can place. For example, if the equipment bag is designed to place the MP5 magazine (ammunition specification is 9mmx19), it is unlikely to put the M16 magazine (ammunition specification is 5.56mmx45) into it. On the contrary, the equipment bag where the M16 magazine is placed can place the MP5 magazine. Therefore, when you choose a tactical vest, you must consider the size of the equipment you will place in the future. For example, when you are engaged in a paintball survival game, you must choose an equipment bag that is large enough to hold the reserve cartridge. The technical requirements for sewing the vest are also very high. Even if the line with the highest tension level is used, at least two to five lines of line must be used to make the minimum load capacity of the vest more than 70 kg. As for the "spareribs" used by seals, the most common way is to quickly insert and pull apart the buttons. The devil patch is also a "button" widely used in tactical vest equipment bags. In addition, the new tactical vests (commonly known as chops) used by the US Navy Seals Task Force (USNAVYSEALs) use special silent buckles to minimize or even mute the noise generated by picking up items in the equipment bag, so as to facilitate the confidentiality of the task. This is the latest design, but the relative manufacturing cost has also increased a lot.
