LM-432 crab droid/Legends

"Crab droids have a subpar targeting percentage, but deliver a profit of forty-eight-thousand credits per unit. They might not win the war, but they could save the Techno Union's fiscal quarter."

LM-432 crab droids were battle droids used by the Confederacy of Independent Systems during the Clone Wars. They were nicknamed "muckrackers" because of their extensive use in marshy terrain. Their name was derived from their six-legged scuttling movement.

As well as their powerful pincer legs, LM-432 crab droids were armed with twin blasters. They were also equipped with a vacuum pump system integrated into their forward pincers, which could suck up mud and then spit it out to either clear space for Separatist forces or obscure the visual sensors of enemy forces. This earned them the nickname of "muckracker".

LM-432 units were covered by armorplast-shielding that could deflect blaster shots. The largest legs of a LM-432 unit were tipped with heavy duranium stabilizers that could secure purchase on even bedrock.

Crab droids were first deployed in conflicts on marshy worlds, but their ability to cross difficult terrain and even scale jagged surfaces led to their usage elsewhere, such as at the Battle of Utapau.

Other variants of the LM-432 crab droid included tiny models for espionage and giant versions that served as mobile armor. One rare variant was equipped with Gungan bubble wort projectors that could imprison their targets in force fields.

Following the execution of the Separatist Council by Darth Sidious's new apprentice, Darth Vader, these units were de-activated.

Some units would later be utilized in Imperial Academy live fire training sessions, and would be among the inspirations for the Imperial MT-AT walker.
