У тактических (баллистических) шлемов уровень защиты обычно классифицируют по стандартам баллистической стойкости. Наиболее распространённые системы — , и иногда .
Ниже — практическая классификация, которая используется у военных и производителей.
1. Level I (NIJ)
Минимальная защита.
Останавливает:
.22 LR
.380 ACP
Назначение:
учебные или полицейские задачи
защита от слабых пистолетных боеприпасов
Фактически: почти не применяется в военных шлемах.
2. Level II (NIJ)
Останавливает:
9×19 mm FMJ
.357 Magnum
Назначение:
полиция
охрана
старые модели шлемов
3. Level IIIA (NIJ) — стандарт современных боевых шлемов
Останавливает:
9×19 mm
.44 Magnum
большинство пистолетных боеприпасов
Типичная защита:
осколки артиллерии
вторичные осколки взрывов
пистолетные пули
Примеры шлемов:
Это основной уровень для армии и спецназа.
STANAG 2920 (NATO)
Здесь используется V50 — скорость, при которой 50% осколков пробивают шлем.
Типичные показатели:
ШлемV50старые кевларовые~580–600 m/sсовременные UHMWPE~650 m/sтоповые~700+ m/s
Это показатель защиты от осколков, что на поле боя важнее пистолетных пуль.
Важно: что шлем не держит
Даже лучшие Level IIIA шлемы обычно не выдерживают:
5.45×39
5.56×45 NATO
7.62×39
7.62×54R
То есть винтовочные пули.
Исключения — экспериментальные тяжёлые шлемы.
Материалы
Современные шлемы делают из:
Kevlar (aramid)
UHMWPE (ultra-high molecular weight polyethylene)
гибриды
UHMWPE обычно:
легче
лучше держит осколки.
Типичный вес
ТипВесKevlar1.4–1.7 кгUHMWPE1.1–1.4 кг
💡 Практический вывод:
На войне (включая российско-украинскую) главная задача шлема — защита от осколков, потому что 60–80% ранений головы происходят именно от них, а не от пуль.Если нужно — могу разобрать ещё:
реальные шлемы ВСУ и НАТО
китайские и российские аналоги
какие модели реально лучше на фронте
миф о «шлем держит автомат».

Update. The report the #Trump #DOJ just took down was originally released in June 2024, during the #Biden administration. But the Biden National Institute of Justice (#NIJ) wasn't the only research org to conclude that most domestic terrorism in the US is from the right wing.
The conservative #CatoInstitute (@cato) reaffirmed that conclusion last week.
According to Cato research, there were 620 politically-motivated murders in the US in the last half-century. 391 were from the right and 65 from the left. (The rest were from Islamism, separatism, or other ideologies.) Politically-motivated right-wing murder is more than 6x as frequent as politically-motivated left-wing murder.
These numbers do not count the deaths from the 9/11 attacks because they were not domestic terrorism.
See the numbers in the Cato Institute report from last week …

"DOJ Deletes Study Showing Domestic Terrorists Are Most Often Right Wing."
https://www.404media.co/doj-deletes-study-showing-domestic-terrorists-are-most-often-right-wing/
(#paywalled)"The Department of Justice has removed a study showing that white supremacist and far-right violence 'continues to outpace all other types of terrorism and domestic violent extremism' in the United States. The study, which was conducted by the National Institute of Justice [#NIJ] and hosted on a #DOJ website was available there at least until September 12, 2025, according to an archive of the page saved by the Wayback Machine. Daniel Malmer, a PhD student studying online extremism at UNC-Chapel Hill, first noticed the paper was deleted."
