Since I did entirely too much thinking on this topic for the sake of the fanfic, I'd like to present my go at the HWP chapter.
1004.5 HWP Team
The Mobile Heavy Weapons Platform, or HWP, is a remotely operated armoured robotic chassis. Using standard comlink frequencies and an encrypted control channel, the HWP operator is able to achieve tight interaction with the rest of the squad despite being in a remote physical location. The HWP sensor suite gives the operator visual acuity equivalent to the soldiers on location. The HWP chassis is 1.2 meters wide by 1.5 meters long by 1 meter high. It is capable of 40 km/h speeds and has a 100kg load capacity for ammunition. It is often referred to as a miniature tank and can be used in similar roles.
1004.5.1 Main roles
High speed allows recon over wide region. Care must be taken to not get so far ahead that the HWP cannot be supported by the rest of the squad.
The high speed of the HWP enables it to cover ground quickly and establish presence in flanking positions, supporting further squad movement.
1004.5.1.3 Forced Entry
The main advantage here is that where loss risk is high, the HWP can be used as the breaching unit in order to protect the more valuable soldiers. Combine with other tactics such as smoke. Remember the tank is not as manuverable as a soldier and passageways may have to be widened for access.
1004.5.1.4 Hostile Area Deployment
Similarly the HWP, when placed at the exit ramp, can save lives by being the first unit deployed into hostile landing zones. The HWP should seek to establish as many enemy positions as possible before returning fire.
1004.5.1.5 Heavy Weapons Support
Surprisingly a little used role, the HWP can offer HW support to fireteams without a HW component and can even make use of its speed to support multiple teams by travelling between them.
Recoil design constraints limit the size of the armament for the HWP platform. The following armaments have been approved for field use.
1004.5.2.1 Cannon 25mm (M242 Chain Gun)
The 25mm high velocity round provides firepower between that of the Auto and Heavy cannon in damage capability. 50 round magazine. Single-shot mode only.
1004.5.2.2 Rocket 66mm (M202 Quad Launcher)
The two quadruple rocket pods provide 8 high explosive rocket munitions. Firepower is approximately equivalent to the Small rocket for man-portable rocket launchers. Should never be left to reaction-fire in close situations.
Firepower similar to Portable Heavy Laser, improved X-Alloy armour.
Standard model comes with Hoverdrive, Eleurium use negligible.
A lighter rating of Blaster Launcher weaponry, shares programmable projectile path ability for indirect fire. Ammo capacity similar to Rocket tank. Same warnings apply.
