Guardsmen are heavily augmented Grineer melee units wielding the  Amphis staff. They can most commonly be found in the Grineer Shipyards on Ceres.
Tactics
Claimed to be "Vicious Melee Fighters" by the Lotus, the Guardsmen are true to their description.
- Like traditional Melee units, they will often use rush tactics and overwhelm their targets with a quick flurry of strikes.
- These and the Bailiffs are the only type of Grineer units that can parry attacks in front of them, which makes solo battles difficult as these would simply chase their lone target.
 Excalibur's
 Radial Blind and
 Inaros'
 Desiccation make them exposed to finisher attacks.
Farming Locations
These are based on opinions and may not be 100% true. These should be viewed as advice for finding the enemies until better facts are proven.
Target | Planet | Name | Type | Level | Tile Set |
---|---|---|---|---|---|
Ceres | Lex | Capture | 14 - 16 | Grineer Shipyard | |
Ceres | Nuovo | Rescue | 13 - 15 | Grineer Shipyard | |
Ceres | Ludi | Hijack | 15 - 17 | Grineer Shipyard |
Prosecutor Variant
Prosecutors are elite Guardsmen hand-picked by Councilor Vay Hek. They have a 100% chance to drop  Javlok Capacitors on death.
- Prosecutors are made unique by elemental shield auras that they use. There are four kinds of Prosecutor, one for each of the four base elemental damage types â
 Heat,
 Cold,
 Electricity, and
 Toxin. They project an aura that sets allies Damage Type Modifier to physical and non-combined elements to -100%, and gives -85% Damage Type Modifier to combined elemental damage types, but sets allies Damage Type Modifier to the corresponding non-combined element to +100%.
- All increases or decreases are multiplicative to health and shield damage type modifiers.
- Multiple Prosecutor auras stack.
 Void damage can also deal damage to Prosecutors of any type.
- Prosecutors are likely to spawn after alarms have been triggered.
- Prosecutors can share their immunity buff with Tenno should they be allied with the Tenno, such as when summoned through
 Nekros's
 Shadows of the Dead or during an Invasion when the player has sided with the Grineer.
- Prosecutors are considered Eximus units for all purposes (for example, dropping
 Carbides on the Grineer Shipyard tileset).
- Prosecutors are most commonly found in the Rescue mission Nuovo on Ceres. The Lotus will warn the Tenno of the Prosecutor's appearance. They will then be found patrolling the area, near the prisoner.
