Classification of Bulletproof Shields
Bulletproof shield, as its name implies, is
a shield with certain bulletproof ability. The traditional bullet-proof shield
is a rectangular sheet with radian, usually with handles behind it. Whiling
fighting with enemies, the holders can cover his head and body with such a
shield, which can provide enough protection area for them. However, with the
continuous progress of the protection industry, various protective products are
also experiencing constant change. Their function, appearance, and use design
are also constantly improving, and becomes more and more in line with people’s
usage pattern.
At present, many materials that can be used
to make bullet-proof shields, including Kevlar, polyethylene, ceramics and
steel plates.
Based on the protection area, bullet-proof
shields can generally be divided into five sizes, super-small (450mm * 650mm),
small (550mm * 650mm), medium (550mm * 1000mm), large (600mm * 1300mm) and
super-large (600mm * 1750mm). The National Institute of Justice has set seven
levels of standards for bullet-proof shield, i.e. I, II, III A, III, IV and
Special Level. Level I shield can stop 0.22 pistol bullets and 0.38 special
pistol bullets; level II can stop 0.357-inch Magnum bullets and 9-mm pistol
bullets (such as 9mm Barabarum bullets with higher initial velocity); Level III
A can stop 0.44-inch Magnum bullets and 9-mm submachine gun bullets; Level III can
stop 0.308-inch Winchester full armored bullets and 7.62-39-mm bullets; Level
IV can protect 0.30-06-inch bullets, 7.62-mm NATO-made penetrators and 7.62-mm
R bullets. Bullets; special grade is customized for special bullets. Special
police officers have good access to bullet-proof shields, but what they use
mostly are medium-sized shields, which can be equipped with tactical lights
sometimes. They are mostly level IIIA, occasionally level III.
According the shape and design, they can
also be divided into several categories, including hand-held shields, folding
shields, briefcase shields, ladder shields, and shields with trolley.
Hand-held shield
Hand-held shield is the most common shield
with two handles in the back, which can be used by both left-handed and
right-handed users. There is usually a bullet-proof speculum to facilitate the
observation of external conditions. This shield can adapt to more complex
terrain and combat scenarios, such as in narrower staircases or corridors, and can
also better cooperate with guns and other weapons.
Shields with trolley
This bullet-proof shield is equipped with a
trolley, which saves much labor for long-distance transfer. In addition, they
can also be equipped with handles and speculums. As we all know, the higher the
protection is, the heavier the shield is. So, a trolley is necessary to make a
high-level shield be transferred easily. This kind of shields is applicable to open
battlefields. When the terrain becomes complex, where the trolley is not
convenient to be used, the shields can also be used alone.
Ladder shields
This shield can be transferred to be a
ladder by its special structure design, which facilitates users’ climbing
during a battle. In addition, there are also wheels at the bottom of the ladder
shields, by which the shields can be moved freely.
Briefcase shields
As the name implies, this shield is like a
briefcase in appearance. But in emergency, it can be unfolded quickly into a complete
shield. This shield weighs only 5 Kilograms, but is strong enough for stopping
light weapons like pistols.
