  1. There is a long standing issue where limited extent 'thin' surfaces hit nearly parallel act as 'infinitely' thick. Frequently seen with ATGM or large APFSDS hits on track or trackguard (or at the hull top in the way of the turret ring), where even BMPs will sometimes 'bounce' a shot.

    The maximum extent of armour from such an impact should be the LOS front-rear distance along the trajectory, rather than the naive thickness/cos(alpha), IMO.

  2. Not sure if it is left wing. Certainly a rush towards authoritarian control with a feminist bias. (This bias *is* left wing, but it is melded with centrist and right wing ideologies with a broad appeal to the unthinking masses).

    I dislike that every time I carry swords to fencing school I am 100% breaking the knife crime laws (3ft blades being significantly longer than the 3" limit, and the blades not being folding). That I have a "defence" for carrying for the purposes of education, re-enactment and that the swords are designed to be safe in both the cut and thrust isn't much comfort as it is no protection against an arrest (and the seizure of the swords, and search of my home) if some police officer takes it into their mind that they want to target me, or if some other citizen is 'fearful'.

    I dislike that I may not speak freely, risking arrest for "hate crime", 'even if no crime is committed'. That harassment laws are being trivialised to the point of a single complaint (not even by the 'target') is sufficient to prosecute, even if no offence was taken by the 'target'.

  3. Hmm. Debit card and credit card are largely interchangeable here (apart from some details of consumer protection (higher on credit cards), with debit cards also being considered equivalent to cash with no surcharges permitted). I've always made payments on the Esim store for upgrades using my debit card with no issues.


    Most are even provided for the banks by the same companies as those common for credit cards (here Visa and Mastercard, with debit cards also being considered equivalent to cash with no surcharges permitted). A few credit cards, such as American Express have much higher transaction fees and are not accepted by many retailers.

  4. Perforation limit of long rods is not only sensitive to hardness, but also to angle of impact. From the Odermatt form:

    The typical values given seem to be reasonable* for high obliquity impacts (where the perforation LOS is maximum just before the onset of ricochet), but could be 17% lower near the normal impact condition into RHA targets.
    * That is that the penetration values quoted are met with the best estimates of the penetrator dimensions, while at lower angles the penetrations are much lower...

    A 1:1 penetration limit to penetrator length at the normal impact is consistent with a 1.2:1 perforation limit to penetrator length at 65 degrees, going through a plate with thickness of 51% the maximum penetrable.

  5. While sometimes the SB AI is particularly prone to drive into water, this does still happen in real life as well - tanks are bogged, roll over, belly up and all manner of other immobilisations are possible. This is why there is training in self recovery, and a (barely?) sufficient supply of recovery assets.

    To prevent it occurring even when the plan is rushing large numbers of vehicles through difficult terrain at a high speed would be as wrong as the current occasional "deliberate suicide by water" as a vehicle attempts to use the river bank as a firing position.

    Hopefully the higher terrain resolution will also (eventually) permit better shaping of the river bottom/bank/approach which will frequently offer other better fighting positions than our current double v sections do, and less likelihood of drowning in all rivers, all the time, while preserving rivers and lakes as a barrier to movement (even for amphibious vehicles in many cases due to exit requirements).

  6. You can't fire 3km when the covered approaches to your position are averaging significantly less than 2km - down to less than 500m in many cases. The relatively few locations with really good lines of sight are also obvious and likely to appear prominently in artillery fire templates, plus may be easily flanked. ATGM can have longer ranges than tank guns - up to 5km for land based systems of the cold war and up to 8km for helicopter systems which can be a threat to tanks occupying positions with long range lines of fire.

    SB maps are simplified (and distant clutter is hidden) to that lines of fire are artificially longer than reality and covered approaches are scarcer, but in the real world it isn't a given that long range fires will be possible.


  7. 1978 build M60A3 would use a pair of II periscopes for gunner and commander (M35E1 and M36E1) before the upgrade to TTS (from late 1979)

    So not really IR sights - but rather a Passive sight using ambient light.

    RISE Passive seems to be IR periscopes (M32, M36) similar to those fitted to Txx series vehicles with active/passive IR capability over short ranges.

  8. Not cast iron, Cast steel of good armour quality, if a little soft.
    Soviet cast steel was typically a little harder.

    Typically cast armour steel is assumed to be between 85 and 100% of the equivalent thickness of nominal RHA (BNH 270) of similar composition, depending on relative hardness/shape/homogenity. Softer, more ductile armour does tend to spall/fragment slightly less when perforated - a lesson the US designers carried on from WW2 experience, and the survivability improvement when perforated was probably more important than the marginal loss of thickness in an era of HEAT and other 'unstoppable' threats of small diameter.

  9. It is because like the Chieftain (L15 1800m - relatively in the context of other contemporary tank guns (115mm 2000+, 100mm 1500, 1700+, 105mm 1800 - 2500 or more, 125mm 2200+)), the ammunition range is set to 'close only' (1000m for AP) while the HMG are 1500-2500m, and battlecarry is AP by default

    If you can force firing it will remove the carried AP round and permit "less effective" fires using HESH/HE to 4000/3500m - useful against stationary targets only.

    I would prefer a preference to select suitable targets by range and moving status as well as ammunition capability (avoiding frontal engagement with weak AP at extreme range, avoiding engagement of movers above moderate/short range with HE/HESH, reserving these rounds for area fires, or for point engagement of stationary targets and engaging other valid targets first, and other sensible commander decisions within the battle context (maybe ammunition orders and engagement sequence that favours lethality of the current round while still servicing the 'next' important target).

    Even in a "proper army" fighting a war "the proper way" there will be periods of transition, e.g. when a new, better type of ammo is SUPPOSED to replace the old type, but production has just started. In such a situation (e.g. Operation Desert Storm) it seems like all available "new" ammunition is handed out in small quantities (M829A2, then nicknamed "silver bullet") whereas the old type would still dominate the loadout. Syria today appears to be just a crazy mess.


    That said, Steel Beasts CAN simulate this to a degree with ammo slots #3 and #4 in the Mission Editor's Ammunition control dialog; slots three and four can be of any type.

    Wasn't silver bullet the M829A1 issued alongside the M829 because of concern over the strength of or upgrades to T72 and T55 armour (T72M1 turned out to be no real problem but some of the T55 packages were competent upgrades (although they did compromise the mobility somewhat)).

    When a HEAT rounds hits an APC, the warhead detonates, the liner collapses, and a big stream of vaporized copper, hot gas, plasma, and chunks of armor come blasting through the hull with much more effect than would have happened if you'd shot it with a sabot.


    The HEAT jet and slug are actually solid copper (or other lining material) that has flowed under high pressure. It isn't 'molten' by a conventional definition of being above melting point temperature, and very certainly isn't a vapourised form.

    In essence it is a dynamically formed, unstable and extreme elongation 'long rod' using a shaped explosion front to focus a warhead liner into a penetrator. Differences also include a velocity gradient between tip (very fast) and base (fast), and that the majority of the mass is in the slug which travels very much more slowly behind the jet.

    EFP does a similar thing, but uses more material, formed into a longer ranged, more coherent and stable but shorter and bulkier projectile.

    I,m not an expert or experienced militarist, but I feel that the top speed of vehicles in game are not related to each other. Example: Should the Centauro and other light infantry vehicles not be much faster then a M60, or other main battle tanks? o.O


    Yes, when driving flat out on a road. Not when performing an administrative march in column with mixed vehicles, not necessarily when on soft ground or in dense vegetation.

    If you set the appropriate movement orders most of the wheeled vehicles will drive at 80-120 kph on roads...
    However do note that some MBT can achieve high 70s/low 80s... and they will perform relatively better in poor going too.

    In march orders *everything* moves at 20 kph/30kph/50kph regardless of it's maximum potential though.

    Doctrines were made by People sitting on a wooden Table, not by Tankers sitting on a Steel Beast.


    If it is possible to make the decisions on Battle Field by a Tank, why still Men are is sitting inside ?

    You (afaik) didn't operate vehicles with CITV and GPS TIS.
    To compare the requirement of older vehicles and very modern ones to use vision blocks or unbuttoned commander is slightly misleading if you ignore this difference.

  14. Is it possible to force the AI to drive on the left hand side of roads where that would be appropriate? (A per-map option?)

    I understand that most countries drive on the other side, but there are some places which have a drive on the left traffic system.
