    I'm not being rude here for what its worth but it would appear I was taught incorrectly and have taught incorrectly myself following that then in that case (basic training, 1st class private and NCO's cadre) however the 3rd picture Kiory put up is the better one for an example of what is correct. My point was if the eye relief is 25mm the depth of the eye piece must have been at least 20mm from the lens.

    Just out of curiosity, what Reg' were you in?

    As a point of interest (or not :P) if you're too far from the sight you cannot ensure the outside circle of the sight picture is all solid. If its solid and not blurred your sight picture is perfect which is a big deal at 400m. I'm prob paraphrasing here but "Ensure sight alignment i.e sight picture is correct" this is the point in a rifle lesson you'd go through the eye relief distance and position on the cheek piece.

    What you're talking about is Parallax error and it happens when you're too close to the objective too, not just when you're too far away. The human pupil can only accept it's own size in light, which is why the exit pupil for the SUSAT is 6.3mm. Go too close to the objective and you'll have a parallax error, which means each shot placement will be completely different at 400m, unless you can re-place your eye in exactly the same place, with no error (physically impossible as human beings). Go too far away and exactly the same will happen.

    I never had my eye resting on the rubber surround of the sight unit, I always observed it as a bad habit - but if it worked for them, why not? It is however, an incorrect principle.;)

    Do you know if overall, the version 3 PPVs have a taller rear cab as well?

    I remember the ones we were "looking after" in my old job all seemed to have a couple of inches extra headroom over the older vehicles I'd been in (didn't feel the need to stoop so much). However, that may have been 'special' due to the frequency at which blokes would be standing up and walking around inside, as they were deffo fitted out as EOD role and Command role vehicles and not PPVs. They had hardly any seating inside for starters. :D

    Aye I know; what I was implying was that the spec for the vehicles carrying out those two C-IED roles is different, and they're generally marked down separately as two sub-variants of Mastiff.

    The cab is definitely larger/higher. I've not been able to work out which. You're spot on with regards to not having to stoop as much as the Mastiff 2. I know that the interior was re-designed and a lot of space was saved with things being tucked away. A few lads were injured with bit's of kit flying around that weren't secured after IED strikes, so each bit of kit has it's own secure spot in the vehicle now. I think that's attributed to the larger feel.

    Apart from having a cheeky nosey around the Mastiff 3, the only real experience I have is with the Mastiff 2 and I can certainly see a lot of differences, especially internally.

    With regards to the C-IED variants, internally they are worlds apart from the PPV model. I'm trying to do a variant with the C-IED specs. but I'm dubious about including any of the internal ECM equipment for OPSEC. We'll see how it goes. I'm mainly going to concentrate on the PPV model as it has a larger audience at the moment.

    Just an interesting video. Gives you an idea of the extra space even with the rear seating in place.

    What site/images did you use for references when making the model?

    I just ask because some details are missing that would normally distinguish the Mastiff 3 from Mastiff 1 and 2. Namely that Mastiff 3 has side-doors for the driver and commander (like Wolfhound TSV), which lead to a rather significant redesign of the armour modules around that area.

    It's possible that whomever you got the reference material has misidentified a Mastiff 2 as a Mastiff 3 is all; particularly as Mastiff 3 is a scarcer beast then its predecessor, and IIRC most of the vehicles of that spec ended up in more specialised roles like EOD, ECM, Command etc. rather than as PPVs.

    However, it's a nice model of a Mastiff. Good job! :)

    Hey Monkey,

    They're actually picture taken of current Mastiff 3's. They still do fill out the PPV role, however I'm aware a lot went to more specialised mounted regiments. The Driver and Commander doors are still to go on. The only significant difference on the outside of the vehicle are the small gaps left for movement on the outside and the retainers for the plates. It's internally that you see the major modification for the redeveloped armour around the doors.

    Also, the rear cab is very different internally, which is one of the main differences between the Mastiff 2 an 3.

    There is plans of releasing both a Mastiff 2 and 3. But I'll have to see how much time I have.

    Many thanks for the heads up, thanks for all the kind words.

    PS, EOD/ECM fall under the same remit, they are both C-IED.

    7XBRF - GU Mod Team are happy to relase the first renders of the 7XBRF - GU Mastiff 3 Protected Patrol Vehicle (PPV), used by the British Armed Forces and currently in theatre in Afghanistan.

    'Mastiff is a heavily armoured, six x six-wheel-drive patrol vehicle which carries eight people, plus two crew. It is currently on its third incarnation.

    It is suitable for road patrols and convoys and is the newest in a range of protected patrol vehicles being used for operations.

    With a maximum speed of 90 kph Mastiff is armed with the latest weapon systems, including a 7.62 mm general purpose machine gun, 12.7 mm heavy machine gun or 40 mm automatic grenade launcher.

    These wheeled patrol vehicles have a less intimidating profile than tracked vehicles and give commanders on the ground in Afghanistan more options to deal with the threats they are facing.

    They have Bowman radios and electronic countermeasures and are fitted with additional armour beyond the standard level to ensure they have the best possible protection.'

    The Mastiff 3 will come in several different variants with different weapons platforms, including the 7.62mm GPMG, the 12.7mm Heavy Machine Gun (HMG) and the 40mm Grenade Machine Gun (GMG). One of the Mastiff 3 Models will be equipped with the ROTAS Mast - Mounted - Sight system.

    Here are some HD renders of the 7XBRF - GU Mastiff 3 WIP.
