ESU-S4x-023 Whisper II

Armaments
- KT-060 Carbine w. Suppressor: A modified 60mm Carbine that serves as the Whisper II's primary ranged weapon. Its semi-automatic armor-piercing receiver gives a skilled pilot just enough firepower to dispose of opponents at medium to long range. The suppressor further shields the Whisper from detection.

- Anti-Armor Stealth Blade: An updated and more simplistic version of the Whisper's Assassin's Retractable Dual-Blade Gauntlet. In replacing the two razor-sharp retracting blades with a single one (mounted on a rotating hardpoint), it reduces the overall bulk placed on the machine's right arm. When paired with the equipped Hi-Sensitivity Targeting Visor, the Whisper II can target enemy machines' joints and other vital areas for quick dispatching. While a heated variant was designed for use by the Whisper II, it was deemed compromising of the Unit's stealth capabilities.

- Anti-Armor Knife: Similar to the ones used by Harbinger Ground Types in the FCG, the Whisper II is equipped with a pair of small knives. Each is stored in a calf-mounted mechanism that extends them out from a hidden compartment, allowing for easy access and quick reaction. These were added to act as a backup weapon, should the Whisper II's primary weapons be compromised.

Special Equipment and Features
- Stealth Drive MKII: Mapped throughout several hardpoints on the Whisper II's armor are sound-suppression nodes. These muffle all thruster and movement sounds made by the Whisper II when use, ensuring that motion/sound tracking devices cannot detect the machine.

- Cloaking Drive MKII: This upgraded version of the Stealth Drive from the original Whisper sports a stronger and longer lasting invisibility device compared to the original. While still retaining the distortion when moving, it makes the machine completely invisible when standing still. Unlike the original, the device consumes power independently from the Whisper II's Fusion Drive.

- Hi-Sensitivity Targeting Visor: This advanced version of the Assistive Targeting System has been equipped with not only a standard targeting interface, but also an additional long-range targeting interface. Unlike its standard counterpart, the long-range comes in the form of a slide-down visor that shifts over the eyes. This almost doubles the range at which the system can track targets.

- Utility Cloak: In the case of the Cloaking Drive being disabled, a large reflective "cape" can be draped over the Whisper II to cover the machine's profile. While not retaining any mechanical properties, it still provides a level of stealth in certain conditions. Depending on the area deployed, different shaded cloaks can be used.
