That’s       a humvee or equivalent, with appliqué armor. Maybe a LAV. If you wanted to       carry a full squad of dismounts, that’d be something like a Stryker vehicle       or a Bradley. Humvees, LAVs, and Strykers are wheeled, Brads are tracked.       Wheeled vehicles tend to be faster and more reliable. Tracked vehicles are       more complex and more likely to break down. They give better cross-country       performance and are more agile.       >       > Terrain is mostly woodland, rural and praires, but it would be good if       > vehicle could travel easily in other environments after small modifications       > (sand / snow tires maybe?)              still a humvee or a LAV       >       > Opposition is supported by many locals, with some areas being more       > supportive, while others not.

(Imagine Allies and Axis stopping       > military actions and switching to winter tanks after first snow :p)              ah... that’s exactly why weather/climate conditions are so important.       German AFVs encountered severe problems due to mud in the autumn of 1942 and       snow in the winter of 1942. Older vehicles (PzKw III and IV, and any vehicles       based on their chassis, of which there were many) continued to have problems       even after some modifications such as wider tracks (reduce ground       pressure...). Newer vehicles (PzKw V ‘Tiger’ and PzKw VI ‘Panther’,       and vehicles based on their chassis, of which there were many) had wider       tracks from the start. Not wide enough, especially the Tigers, but were more       easily upgraded. Unfortunately, they were also bigger and heavier, so there       were still problems when compared to the performance of Russian T-34s,       designed from the outset for Russian conditions. Then there was the fancy       interleaved suspensions used by both Tigers and Panthers; there would be a       reason why no-one uses that kind of thing any more. Among other things, the       road wheels would freeze together in very cold weather, and would jam if       enough mud got into the right (wrong...) places. The Russian designs worked       fine in Russia, but had problems elsewhere. (Sand got into places it       shouldn’t, resulting in breakdowns; in addition, designing for cold weather       has consequences when things get hot.)       >       > The enemy uses IEDs, yeah, roads outside of towns are mostly dirt/gravel.              Something like the American MRAP or the South African Buffel or Mamba might       be effective. The South African Ratel might also be a contender.       >       > Air transport is reserved for wealthiest, water transport is popular for       > transporting goods and people. Inside towns roads are hard.       > Vehicles must be very reliable, their radius of operation must be quite big.              That leaves out the Strykers, then. You’re looking at something like a       Mamba or a Ratel at the high end, or a LAV at the low.       >       > They need to carry just equipment and consumables for crew.              Mamba or Ratel.       >       > Communication is by satellites and radios.

Main armament,       20-35mm fully automatic cannon, remotely fired from inside the main hull.       Used in both anti-vehicle and anti-personnel roles.Secondary armament,       multi-tube ‘pepperbox’ laser, primarily point defence against inbound       anti-vehicle missiles. Limited anti-vehicle/anti-personnel capability.       Rifle-caliber machine gun co-axial with main armament. One/two additional       machine guns, hand operated, on external mounts. Crew of four: commander/main       armament gunner, driver/tactical navigator, electronic systems/air defence       operator (laser gunner), mechanical systems/loader. Four-six dismounts.       Dismounts operate the hand-held machine guns, which can be removed from the       external mounts. Diesel or diesel-electric power systems. All wheels       steerable. Armor sloped to redirect blast from mines. Can lose one, perhaps       two if eight-wheeled, wheels and still operate. Wheels solid rubber or spun       fibre. Basic vehicle would be standard troop carrier. A line platoon would       need five-seven, probably six. A line company would have three line platoons,       one heavy platoon (mixed mortars and basics), a support group (mixed heavy       and basic) and a command group (command, air defence, a basic). A scout       platoon would be two pink teams, three scouts and a heavy each. Scout       platoons might be attached to line companies, might be independent, would be       part of battalion assets. A line battalion would be three line companies,       two-three scout platoons, a heavy company (mixed mortars, heavies, basics)       and a command group, two-three command vehicles, an air defence vehicle,       heavy, two-three basics. combat engineer and mine warfare units could be       attached at company but more likely battalion level. given scenario,       brigade-level operations unlikely.              scout vehicle: as basic vehicle, closer to 5 tonne. 20-mm gun. Four       dismounts. Use extra space/weight to carry consumables. Operate in groups of       three. may have light UAVs.              mortar vehicle: main armament removed, replaced by semi-automatic mortar,       80-120-mm, and ammunition. no dismounts. Mortars operate with main force,       never go out alone as they have no dismounts.              heavy support vehicle: main armament removed, replaced by 90-mm       remote-operated direct-fire gun. No dismounts. Heavy support operates as       fourth member of scout team, covering the scouts, and in support group with       main force. Never go out alone, as have no dismounts.              Note: as air/artillery/orbital support is limited, organic artillery in form       of mortars and direct-fire guns essential.                     [continued in next message]              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
