hastati

Hastati (: hastatus) were a class of infantry employed in the armies of the early Roman Republic, who originally fought as spearmen and later as swordsmen. These soldiers were the staple unit after Rome threw off Etruscan rule. They were originally some of the poorest men in the legion, and could afford only modest equipment—light chainmail and other miscellaneous equipment. The Senate supplied their soldiers with only a short stabbing sword, the gladius, and their distinctive squared shield, the scutum. The hastatus was typically equipped with these, and one or two soft iron tipped throwing spears called pila. This doubled their effectiveness, not only as a strong leading edge to their maniple, but also as a stand-alone missile troop. Later, the hastati contained the younger men rather than just the poorer, though most men of their age were relatively poor. Their usual position was the first battle line. They fought in a quincunx formation, supported by lighter infantry. The enemy was allowed to penetrate the first battle line consisting of hastati, after which the enemy would deal with the more hardened, seasoned soldiers, the principes. They were eventually disbanded after the so-called "Marian reforms" of 107 BC.

==History and deployment== Hastati appear to have been remnants of the old third class of the army under the Etruscan kings when it was reformed by Marcus Furius Camillus. The third class stood in the last few ranks of a very large phalanx and were equipped in a similar manner to hastati, although they were more often than not relegated to providing missile support to the higher classes rather than fighting themselves. Penrose and Southern postulate that it is probable that engagements with the Samnites and a crushing defeat at the hands of the Gallic warlord Brennus, who both used many smaller military units rather than a few larger ones, taught the Romans the importance of flexibility and the inadequacy of the phalanx on the rough, hilly ground of central Italy.
