movement and fortifications

[Siddhi]

A couple of SPMBT (different) design issues that I recently grappled with in designing a scenario. I would be interested in comments.

i. vehicle movement in broken terrain
This has probably been addressed many times already, but I would like to know what the rational (gameplay?) was behind the current vehicle movement capability in broken or restricted terrain. Basically: why tanks (let alone wheeled APCs) can cross wooded terrain. They can't. Not even close, especially if it an old wood / heavily forested. Even a "young" wood with saplings can be dangerous, slipped tracks and lack of traction on broken wood will immobilise most tanks even under these circumstances pretty quickly. Designing a scenario (as I recently did in an upcoming scenario on Wargamer, SPANNOCHI'S DREAM II) with "impassable" terrain as a base for the wood only goes so far, the AI will still try it.

ii. Fortifications
Totally different database issue. For a scenario I felt I had to completely "redo" some of the bunker emplacements in the database; although the armament was mostly correct the hit ratios were much lower then they should have been. To accurately simulate a 1m reinforced conrete, I had to radically raise armour ratios - also, the "turret" rating had to be raised higher then it probably is as the "turrent" in an embunkered position is effectively just the firing slit, i.e. 25-30% of the size of a normal "turret". The size had to be decreased from 2 to 1 to give the bunkers a chance of survival, given that concealment is such a major issue for bunkers I thought it sensible.

iii. vehicle size
Something I have been unable to address but which detracts from gameplay is the none-modelling (as far as I can tell) of different tank sizes, leading to incorrect hit ratios. The T-55 e.g. is a full 40% smaller then a m60 front aspect, how can you have the same hit ratios for it? Many tanks were designed specifically to have a small front aspect, e.g. the Swedish assault-gun type construction of the 1970s with a fixed turrent.

I have a couple more but would be interested to hear if these issues
