which troops are infantry in state of survival

In the close fight, infantrymen must be skilled in the employment of all weapons (rifles, bayonets, LAWs/AT4s, grenades, mines, and even their bare hands). They should also be familiar with foreign-made weapons they are apt to meet in battle. They should be proficient with other weapons in the unit as well as their own. Infantrymen must be proficient in marksmanship, close combat, and fieldcraft. These units are the result of a tough, thorough, and demanding training program conducted by leaders who understand the effective employment of infantry forces. This close personal fight requires combat-ready units composed of skilled soldiers and resourceful leaders. The infantry rifle company is organized and equipped to close with the enemy to kill him, destroy his equipment, and shatter his will to resist. However, the oldest Regular Army infantry regiment, the 3d, was constituted on June 3, 1784, as the First American Regiment.

Ten companies of riflemen were authorized by a resolution of the Continental Congress on June 14, 1775. The Infantry closes with the enemy by means of fire and maneuver in order to destroy or capture him or to repel his assault by fire, close combat, and counterattack.
