What sort of vehicles or tech would logically exist within the Imperial Guard and Space Marine forces that arn't talked about in books?

Basically what I mean is is there an imperial version of a transport truck or something like the M35 (yes I know pic related is not an M35) or would those functions be covered under various variants of existing vehicles?

The reason I ask is it would be interesting to imagine an only war game where you play as the logistics part of the regiment tasks with picking up or fixing vehicles in the field escorting the engineseer and his/hers repair servitors and delivering goods under fire

40k doesn't run on "logically"

Yes I know it does but that doesn't mean we can't discuss it or do you suggest we just perputate the meme version of 40k?

I've actually grown to like the idea of a more pragmatic and slighly functional imperium.

"The Centaur is a light vehicle used to transport men and ammunition or tow light artillery pieces. It is lightly armed with only a single Heavy Stubber, but tends to carry weapons teams and heavy mortars. Although not suited for heavy combat, it is popular with the Death Korps of Krieg. The Centaur saw heavy use during the Siege of Vraks, where thousands of Centaurs were used to transport men and weaponry behind the lines."

afaik in the setting Imperium can't build anything that isn't from a STC, but we could imagine there are thousands of utilitary vehicals STC
It's just that's a nice excuses for GW from doing other kits

>The Trojan Logistical Support Tank is one of the main workhorse vehicles of the Imperial Guard. The Trojan is mainly used to transport supplies from the safety of the supply dump to the front lines. This support vehicle is built using the same chassis and engine as the Chimera armoured personnel carrier, but it trades in its troop space for a supply hold, and possesses an external crane to hoist the supplies out. The Trojan can also be used to transport even larger amounts of supplies than can fit in its own hold on trailers that it tows behind it. Since it is larger than the Centaur utility tank, the Centaur is used to tow smaller siege weapons and trailers. The Trojan is only lightly armed, as it is not meant to be used as a front line combat vehicle. The Trojan is easy to manufacture and is very efficient in its role, but it is unable to tow vehicles due to its rather weak crane system. As such, that task is better left to the Atlas Recovery Tank.

>The Trojan's main purpose is the transportation of supplies and other materiel to the front line, and this can include ammunition, foodstuffs, clothing, water, infantry weapons, and just about anything that is needed, as long as it fits inside the vehicle's chassis. The Trojan has several types of trailers it tows behind it, including a munitions trailer, a fuel tanker, and a general supply trailer. The Trojan can also tow weapons platforms such as the Earthshaker Cannon, Medusa Siege Gun, Quad Launcher, and Heavy Mortar Cannon, which may be too large or the terrain to rough for a Centaur to tow into position. The Trojan can also carry the large shells those artillery pieces require, so that they may never stop firing for want of ammunition. Trojans can be used as command vehicles and communications vehicles if the need arises, and as minesweepers and bridge layers if there is no other alternative.

>The Atlas is an armoured recovery vehicle based on a tank chassis that is used by the forces of the Imperial Guard and possibly other Imperial forces such as Planetary Defense Forces and the armed forces of the Inquisition to recover damaged or immobilised armoured vehicles during and after a battle. The Atlas uses a powerful rear-mounted crane to tow vehicles out of the line of fire and to the field repair shop, where they can be fixed and sent back into combat. Heavily damaged vehicles can be placed on trailers and hauled away by a Trojan to be repaired at a better-equipped facility. The large spade on the rear of the Atlas is used to keep the tank from being dragged backwards by the weight of its target. If a vehicle is completely destroyed, and beyond repair, it is stripped of usable equipment and unfired ammunition, its Machine Spirit commended to the Emperor, and then its chassis is left to rust in peace. The Atlas is mainly used to recover damaged or immobilised tanks from the front where they can be repaired, but it can also be used to simply move a vehicle out of the way of other vehicles, and to move other obstructions. An Atlas is capable of lifting and towing up to one Leman Russ tank, of any variant, but anything larger, such as an Imperial Baneblade, will need to be towed by up to four Atlases to move it even a short distance. A regiment lucky enough to have multiple Atlas recovery vehicles usually groups them all into a single recovery squadron that is directly under the command of the regimental colonel and his staff. The tanks are given out as needed to the various companies.

>The Centaur is a small armoured utility vehicle that is used in a wide variety of battlefield roles.The Centaur is common sight both within the armies of the Imperial Guard and those Planetary Defence Forces with sufficient technologocial knowledge to build them. The Centaur can serve as a Command Squad transport, a communications vehicle, and a supply vehicle, but is most commonly used as an artillery tow vehicle during prolonged sieges of fixed enemy emplacements. The vehicle has a normal crew complement of only two -- a driver and a gunner -- but can be crewed by just one in special circumstances. During sieges the Centaur can tow the lighter pieces of artillery and the crew can ride in the back until they reach their destination. Up to five passengers can ride in a Centaur's crew compartment.

>The Centaur can be used for a large number of logistical purposes on the battlefield, but the most common use is that of artillery tow vehicle. The vehicle has a very powerful engine capable of pulling artillery pieces such as the Heavy Mortar Cannon and the Quad Cannon across the battlefield. It can also tow the much heavier Earthshaker Cannon and Medusa Siege Gun, but only on flat terrain. Passengers in a Centaur can mount any heavy or special weapons they may possess to a mount on the vehicle near the front, adding their firepower to that of the vehicle. A Centaur can also be assigned to a squad of Imperial Guard Grenadiers as a transport. In this case the vehicle is also modified with extra armour plating to protect its crew and passengers from enemy fire. When not being used to tow heavy weapons, the vehicle is capable of moving very quickly, at speeds of up to 70 kilometres per hour off-road. Centaur crews greatly enjoy moving at this speed as it keeps them safer from enemy fire, made reliable by the Centaur's incredibly resilient engine which can run on low-quality fossile fuel.

>The Land Crawler is a Standard Template Construct (STC)-derived vehicle that was discovered at the dawn of the Imperium of Man in the late 30th Millennium by an Adeptus Mechanicus Magos and technoarchaeologist known as Arkhan Land. The Land Crawler is a multipurpose utility vehicle mainly used on Imperial Agri Worlds as a towing tractor or land-moving machine to clear new fields for planting and for transporting the harvest. The vehicle is omnipresent across the galaxy and countless billions of Land Crawlers have been manufactured due to the vehicle's versatility, ease of maintenance, and forgiving driving characteristics. It has been argued by more than one Imperial historian that the humble Land Crawler is the greatest of Arkhan Land's discoveries, even greater than the Land Raider, because after all, even Space Marines must eat!

>The STC design for the Land Crawler, along with the designs for the Land Speeder and the Land Raider, were discovered by Arkhan Land deep within the Librarius Omnis on Mars and all three vehicles were named after him by the Imperial armed forces. All three vehicles were originally known as Land's Raider, Land's Speeder and Land's Crawler.

>While the Land Crawler is designed as a piece of farm or industrial equipment its usefulness has not gone unnoticed by Imperial Guard regiments in need of emergency replacements for vehicles lost during battle. The Land Crawler has been drafted into combat on several occasions, most notably during the Krieg Civil War where the Land Crawler's Siegfried and Bruennhilde variants came into being.

>The Bruennhilde is one of dozens of variants of the Land Crawler utility vehicle commonly found on Imperial Agri-Worlds. The Standard Template Construct (STC) templates for the manufacture of the Land Crawler, along with the Land Raider and Land Speeder were rediscovered at the beginning of the Age of the Imperium in the late 30th Millennium by Mechanicum Magos Arkhan Land, who discovered them deep within the Librarius Omnis on Mars. Unlike the Siegfried variant of the Land Crawler, which was developed on Krieg during that world's 500-year-long civil war, the Bruennhilde was used by the regiments of the Death Korps of Krieg before the war as a light armoured transport. The Bruennhilde is used at present by many siege regiments as an excellent substitute artillery piece tow vehicle when the Centaur is not available. The vehicle is only armed with a single Heavy Stubber and thus is extremely vulnerable to enemy attacks.

>During the 500-year-long civil war on Krieg the Bruennhilde was used to transport artillery weapons such as the Blitzen AA Gun, the Thudd Gun, Rapier Laser Destroyer, and the Gotterdammerung Howitzer to their places behind the lines.
