Arent you forgetting the effect ? Add in the size modifier, the autofire, your chances to affect armor 25 (much less "18") are > 0.
Not forgetting Effect, and never said the chances are 0. I said very unlikely. On 4d6 there is only a 1 in 1296 chance of scoring 24, and a 5 in 1296 chance of scoring 23. My demonstration of a 4d weapon included the Auto bonus, and skill. No size bonus, admittedly, but once you figure in range and movement that more than balances.
There's a higher chance of damaging AR25 with 4d6 than being hit by a meteorite, but I still wouldn't bet on it, and any player who does is likely to die very quickly.

1 hit which can destroy armor (17%), or structure (33%). Totalling, then, there is a 50% chance that a rifle round can affect the whole structure of the vehicle in a non-trivial manner.
Can't destroy Structure - all Hull needs to be wiped out first, so that statement is incorrect. 'Hull' is just a damage sponge to create a delay before the structure gets hurt.

Where does it say there is something better ? "Standard fighting vehicle" I think the rules say.
In what Mongoose Traveller product is the Intrepid in ?
A humvee is a "standard fighting vehicle" in the USMC, as is a Snatch Land Rover in the British Army.
There's no published Azhanti High Lightning for Mongoose yet, but we know that it is on it's way. The Intrepid is a pretty prominent bit of gear for Traveller. Or are you suggesting Mongoose have promoted the humble GCarrier to the Imperium's fiercest fighting vehicle? Any evidence for that is very debatable...

This isnt currently a discussion about AT weapons vs AFV. This has been a discussion about smallarms vs AFV.
smallarms vs. personnel armor = needs minor tweaks
AT weapons vs AFV = might need some changes, but I havnt really run the numbers
smallarms vs AFV = needs fixing to avoid silly results.
Small arms vs personal armour are pretty much spot on. I've thoroughly playtested this over 4 or 5 combats, and
I wouldn't alter them at all. You can if you want to, of course (this is an rpg after all!

), but I'd advise you to do it carefully; Mongoose shouldn't change the mechanics at all.
If you boost the armour ratings of vehicles to make small arms less penetrative, then you will also have to add damage to the heavy weapons, else you'll find they're not hurting what they're meant to often enough. The more dice rolled, the higher probability the results will cluster around the median. With really large numbers of dice, we're talking close to 95% being within a few points of median.
TL6 AT Gun, 6d6, median = 23
TL8 AT Gun, 8d6, median = 31
TL10 Mass Driver, 10d6, median = 39
TL14 FGMP, 16d6, median = 63
Therefore, at TL6, if your tanks have more than 23 or 24 points of armour, they're guns are unlikely to be able to hurt each other, at least on a non-geological timescale.

Doesnt it strike you as somewhat odd that the designers of a vehicle of comparable tech level (12) cant make it immune to smallarms - which is the whole purpose of an APC - much less a tank ?
Firstly, an AFV is not necessarily an APC. Armoured Fighting Vehicle includes things like the Ferret and the Bren Carrier, or a 20's armoured car. Or this: http://en.wikipedia.org/wiki/Fennek

Is the situation any less contrived that shooting your TL 5 rifle through the armor of a high-tech tank ?
A TL5 rifle is not going to seriously hurt a AR18 vehicle, as I showed. It took some minor damage, is all, and that required autofire, which your TL5 rifle does not have. And referring to the AFV or the Hovertrak as a "high tech tank" is misleading. The Hovertrak looks like a poor man's 'tank' at best; suitable for merc outfits and banana republics, but not top of the line Imperial Marines, who will have 'proper tanks'

"A heavily armoured ATV" says the book. It cant be that heavily armored if some schmoe with a TL 5 LMG can blow big pieces off of it.
Well an ATV is little more than an off-road winnabago. Going by it's stats, and performance, it's no APC. That said, the LMG is more like a .50 cal than an M60. By it's description it's uncertain as to whether it is meant to be shoulder slung or just 'man portable', like this: http://world.guns.ru/machine/mg05-e.htm

How do you resolve the inconsistency in knowing that a machinegun is not going to damage a Sherman tank with an AR18 ? (barring a "sensor" hit - we are talking about armor and structure or main gun damage here), yet with the rules, it is quite possible ?
Well I then decided to test my assertion; 3d6 weapons
will not seriously harm AR18, but 4d6 ones will eventually. As long as they're standing right next to it, it doesn't move, and it doesn't fight back. However, AR25 is virtually immune to all small arms. To be more statistically useful we'd need to roll many more attacks than I can be bothered with; I will say that there were more 'high' rolls than 'low' ones; not many but enough to skew the sample towards 'more hits'.

It would appear that you are now agreeing with my general suggestion of "fix the problem", if I am not mistaken.
Mad Dog
I just agree Armour hits are unreasonable for small arms.
Fix a problem if you see one; tweak and fiddle, and tinker, but a demand for a sweeping reform of the system is totally unnecessary.
I suggest that mechanically there is no problem at all; perhaps some of the descriptions could do with tautening up.
In fact, most rpg systems have issues in this kind of area in some way, including previous versions of Traveller; MGT is one of the better ones, IMO.
