Переведите только не через переводчик ! the earliest use of a similar term, known to this author, is dated back to the 1918-1920 timeframe, when noted us small arms designer isaac lewis designed a series of experimental automatic rifles which he called “assault phase rifles”. these rifles fired standard us army issue rifle ammunition of the period, the .30 m1906 (.30-06, 7.62x63mm), and were in direct competition with john browning’s m1918 bar automatic rifle. both lewis and browning automatic rifles were designed to same concept of “walking fire”, originated by the french in around 1915, and first implemented in the ill-fated csrg m1915 “chauchat” machine rifle. this concept called for a man-portable automatic weapon with its primary use being to provide suppressive supporting fire for infantry during assaults on entrenched enemy positions. in fact, this concept called for the “assault” rifle, but its early implementations, such as csrg m1915 and bar m1918 mentioned before, or the russian fedorov m1916, had some inherent flaws.
На самом деле, это понятие называлось так для винтовки "Нападение", но его ранние реализации, такие как CSRG M1915 и упомянутого выше BAR M1918, или Российской Федоров M1916, имели некоторые недостатки.
