AT-AT 

The All Terrain Armored Transport, or AT-AT walker, is a four-legged transport and combat vehicle used by the Imperial ground forces. Standing a towering 15 meters tall, these walkers are intimidating, and are used as much for psychological effect as they are for tactical effect.
An AT-AT has blast-impervious armor plating, and resembles a gigantic beast as it moves across the battlefield. An AT-AT's head carries the main armaments, a pair of light blasters located on the walker's "temples," and heavier, twin laser cannons mounted on the walker's "chin."
The command crew pilots the AT-AT from the walker's head, which is connected to the main body by a flexible neck. The crew consists of a commander, a gunner, and a pilot. Additional crews and troops can be carried in the walker's main storage bay.

standing at attention 

In marching band, standing with your feet together, stomach in, chest out, shoulders back, chin up, and eyes with pride. It is very painful after long amounts of time.

After standing at attention for so long, my legs felt like jelly.
