In 21 BBY, Neimoidian guards were stationed on board the Trade Federation's command ship during the Blockade of Pantora. Some of them were given their own offices aboard the vessel. Jedi Padawan Ahsoka Tano was able to mind trick a guard into letting her and senator Riyo Chuchi enter the detention block. Following the freeing of the kidnapped Chi Eekway, the Federation's envoy and a squad of Neimoidian soldiers arrived at the scene to stop them. To avoid a scandal with the Republic over the Sib Canay's scheme, the envoy allowed them to leave and convinced the higher-ups to end the blockade.
Neimoidian soldiers were also part of the Trade Federation Home Defense Legions that made up the Confederacy of Independent Systems' forces that fought against the Republic's 2nd Fleet, which had blockaded the Quellor sector where the Federation's purse worlds were.
Several of Neimoidian guards were present at a mining complex on Mustafar protecting the Separatist Council. However, when Sith Lord Darth Vader arrived under orders from his Sith Master, Darth Sidious, to dispose of the Separatist Council, the Sith apprentice slew all present.
Following their service to the Confederacy, they were employed as security personnel by House Maccon. In 34 ABY, Lor San Tekka travelled to Cato Neimoidia and entered the Palace of Baron Paw Maccon, disguised as a visitor on a guided tour. However, after finding the Kazerath device which he sought he was arrested by Neimoidian guards.
The Neimoidian Guards aboard the Droid Control Ship orbiting the moon of Pantora wore grey sharp-edged pauldrons, gauntlets and helmets as well as bluish light armor with symbols of the Trade Federation on them and wielded Weequay blaster pistols. The soldiers that participated in the conflict in the Quellor sector and were later seen on Mustafar sported bronze helmets and heavier armor and wielded long blaster rifles. During the Cold war between the First Order and the Resistance, Neimoidian guards in the employ of House Maccon wore grey heavy armor with bronze helmets and the usual long rifles.
