CLEVELAND -- Among the many demonstrations drawing the crowds this week in Public Square are the Marine Corps fire power.

Kids and adults are intrigued by the guns each Marine must train to use.

From automatic rifles to shoulder-launch rockets, visitors can't help but pick them up and squeeze the triggers.

Bomb sniffing dogs are also stealing the show.

Marine K-9s are the front lines of the war in Afghanistan.

There are 647 trained Labrador Retrievers embedded with the infantry.

They are proven life-savers, sniffing out over 100 explosive devices since the war began.
