[Star Wars] Are AT-ATs practical troop transportation? Why or why not?
gpt
Like many things, it depends on the circumstances.  AT-AT's are built, like much of the Empire's war machine, with intimidation in mind, as much as practicality.  Simply as a troop delivery mechanism, there are certainly methods of moving troops faster or moving more of them to any given location.  There's very little, however, than can take a heavier pounding than an AT-AT, and the sheer mental impact of several 20-meter tall monstrosities descending on a defended position shouldn't be underestimated.  It has relatively heavy forward armament, and can deliver 40-50 armored troops.  

Is it the MOST practical troop transport?  No.  It's not particularly fast compared to some, it has no armament anywhere but directly forward, and if they operate without air cover, they are vulnerable to damage or entanglement around the legs.  When it comes to an assault, properly supported, they are pretty damn formidable, and add a hell of a punch against a entrenched position.
