Procured and constructed for Dhon (world) they were designed and manufactured on Seich (world) at TL–11, these 8T G-Carriers are a mainstay of the Dhon Marine Lift Rifle Battalions. Each company has 140 marines and deploys six infantry carriers and a single command version. They are armored, sealed and have life support and airlocks to support Protected Forces operations on the vacuum surface of the tiny colony world of Seich (world) B200668-A. They take advantage of the more advanced fabrication facilities on the colony which are superior to the ones back on Dhon (world). They are on the larger size for Grav APCs in the Distant Fringe and can transport an impressive number of marines. The command version has a potent point defense system which the APCs lack. Crews greatly appreciate the excellent speed of a vehicle this large.

Seich class 8T M-2 Grav APC, TL 10

This new colonial occupation design is pressurized and fully sealed with life support for the three crew and nineteen passengers against the vacuum for service in protected forces environments. It features an airlock and Protected Forces rated crystaliron armor and decent speed. The suite of weapons is fully stabilized and has modern fire control systems. The custom 13.34MW input Plasma Gun is fitted to a fully stabilized turret that is mounted on the chassis deck. It mounts the same artillery system as the much larger TL–9 M150 Colossus class Brigade Transport. There is a laser rifle and a pair of nasty magazine-fed missile tube launchers in the turret as well. The cargo well is often filled with extra fuel for the fusion power plant to extend the vehicle's endurance which is considered short at 14 hours.

Weapons:

Co-Axially Mounted TL 9 Laser Rifle

A Laser Rifle is mounted alongside the custom Plasma Gun. It can be used to designate targets for the missiles on-board. It has a 100-shot battery. The direct fire characteristics are:

Direct Fire Characteristics: Laser Rifle TL 9
Effective Range Long Range Extreme Range
180m (9) 360m (4) 1.8 km (1)

Custom 13.34MW Input Plasma Gun

The plasma gun can engage 1 target per firing phase. It is automatically spotted when it fires. It is fitted with TL–10 direct fire control in a fully stabilized (1mx4.48mx5m turret=22.4m3) turret mounted on the chassis deck. It has 13.34MW input and 2.668MW output. Its direct fire characteristics are:

Direct Fire Characteristics: Custom 13.34MW Input Plasma Gun
Effective Range Long Range Extreme Range
1.6 km (50)3cm(34) 3.2 km (19)2cm(21) 5.5 km (10)-(-)

Flank Mounted 6x6.5cm Multiple Launch Rocket System:

Indirect Fire Characteristics: the multiple launch rocket system has six 65mm tubes, fitted with an auto-loader. It requires a single gunner to operate. They have TL–10 indirect fire control. They use the vehicle's crude TL–5 fire direction center and do not require communication with higher echelons in order to carry out their own single target fire missions. It takes 3.25 turns to set up and has a +2 signature when it fires. It has a +1 to hit DM up to 6km with long range rockets and is -3 to hit up to 12km range. There is storage capacity for 120 of the 16kg rockets within the chassis. They are fitted with HE 14/2/2 warheads and available in:

A full load of the long-range rockets are included in the purchase price. Plans for alternative warhead types are rumored.
Short Range Rockets: 5km/Cr. 64
Medium Range Rockets: 9km/Cr. 128
Long Range Rockets: 12km/Cr. 192

TAC Missiles

There are two magazine-fed 40kg capacity launch tubes in the turret. They use a 6kg 20cm HEAP 52 warhead and there is storage for 20 missiles for each launcher. The typical missile load-out is listed below. It takes a single crew member to manually reload these missiles if additional rounds are available. The homing missiles struggle to achieve intercepts against vehicles protected with advanced ECM abilities. The missiles listed below are included in the price. In general, these missiles can destroy most enemy vehicles they typically encounter but are hampered by their short engagement range.

Characteristics: HEAP 52 Warhead Missiles
Type Range Price
(10) Homing Missiles 21km or 11km w/+10 hypervelocity DM Cr369
(10) Target Designated Missiles 21km or 11km w/+10 hypervelocity DM Cr669
(10) IR Follow-up Missiles +8 HEAP penetration 21km or 11km w/+10 hypervelocity DM Cr469
