Ajax commands his army wielding a huge shield made of seven cowhides with a layer of bronze. Most notably, Ajax is not wounded in any of the battles described in the Iliad, and he is the only principal character on either side who does not receive substantial assistance from any of the gods (except for Agamemnon) who take part in the battles, although, in book 13, Poseidon strikes Ajax with his staff, renewing his strength. Unlike Diomedes, Agamemnon, and Achilles, Ajax appears as a mainly defensive warrior, instrumental in the defense of the Greek camp and ships and that of Patroclus' body. When the Trojans are on the offensive, he is often seen covering the retreat of the Achaeans. Significantly, while one of the deadliest heroes in the whole poem, Ajax has no aristeia depicting him on the offensive.

In Book 7, Ajax is chosen by lot to meet Hector in a duel which lasts most of a whole day.

In Book 14, Ajax throws a giant rock at Hector which almost kills him. In Book 15, Hector is restored to his strength by Apollo and returns to attack the ships. Ajax, wielding an enormous spear as a weapon and leaping from ship to ship, holds off the Trojan armies virtually single-handedly. In Book 16, Hector and Ajax duel once again.

Hector and the Trojans succeed in burning one Greek ship, the culmination of an assault that almost finishes the war. Ajax is responsible for the death of many Trojan lords, including Phorcys. Ajax often fought in tandem with his brother Teucer, known for his skill with the bow. Ajax would wield his magnificent shield, as
