A possible Israeli ground war looms in Gaza. What weapons are wielded by those involved?

JERUSALEM (AP) — An Israeli ground offensive in the Gaza Strip would further escalate the war raging since Hamas launched its unprecedented attack, killing hundreds of civilians. A ground invasion also would threaten to draw in the Iranian-backed Lebanese militant group Hezbollah from the north. The United States has deployed one aircraft carrier group to the region, with another on the way later this week — reflecting concerns of a widening conflict and meant to establish a force that deters Iran and others.

It would be the the third major ground assault in Gaza since Israel left the seaside enclave in 2005.
