[Star Wars] Are snowtroopers, sandtroopers etc specialised infantry divisions that are only deployed to planets with specific conditions or are they regular stormtroopers who are fitted for whatever the conditions demand?

Side question. If they are specialised divisions are they considered more elite and harder to be accepted into?

They're normal troopers in specialised armours. The sandtroopers deployed searching for R2-D2 and C-3PO were dispatched from the Devastator. It'd be fairly silly for Star Destroyers to carry specialised divisions of troops for every possible environment as most of them would rarely see action and be useless. Much better to have an adaptable fighting force in far greater numbers.

The 501st lead the assault on Echo base, as well as the Tantive IV, they were the same soldiers in different equipment.
