The argument about common logistics is cancelled out in true Canadian fashion by the retention and rebuilding of LAV I (6X6) and LAV II (Coyote, Bison) in the system. While I totally understand the impulse (desperation, since the government agreed to buy @ 400 of the required 1400 LAV III variants identified), it really doesn't help anyone except GD, who get nice contracts to do all this for us.
Here is A thought into what versions the other 1000 LAV IIIs "should" be: (add in the Reserve and there would be more than double the number)
LAV III section carrier: similar to the current version, but replaces the turret with an OWS for reduced silhouette, weight and hight.
Coyote IIa recce vehicle; mounts the Delco turret with LLTV or TI sights and carries a four man dismount squad in the back. Partnered with the Coyote IIb, which has a much improved surveillance suite that does not take 30 min to raise/lower. If warrented, a Coyote IIc with an NBC recce suite in the back can also be procured. Coyote IIb can also be issued as the forward observer vehicle for the Artillery.
LAV FS: a direct fire support vehicle carrying a small (60-90mm) high velocity cannon and a generous ammunition load (@ 40 rounds). The gun mount is high angled to deal with those annoying rooftop snipers in an urban fight. The same chassis is also available with a breach loading 81mm mortar (since you can pack a lot more 81mm mortar bombs into the vehicle as compared to the 120mm. Numbers do count).
LAV AT: carries a long range missile system such as HELLFIRE, BRIMESTONE or FOG-M, and replaces LAV-TOW and MMEV, since the missiles can be used direct or indirect and have at least an 8 km range. LAV-AA would use the same chassis if procured.
LAV LOGISTICS: configured like a pick-up truck, would carry pallatized or modular supply packs to support the other versions. A "camper top" would be added for ambulance, CP, mobile workshop and other similar vehicles.
LAV Pioneer: Mostly a light engineer vehicle that can keep up with the rest of the combat team and provide some mobility/counter mobility for the troops. The LAV MRT would be based on this version, and maybe both would be subvarients of the LAV LOGISTICICS "pickup truck".
LAV SP: The 105mm SP version of the LAV III, "just because".
The argument about the LAV being "too complex" for the reserve does not hold a lot of water for me, many armies issue equipment of equal or greater complexity to their reserves (Just walk past the compounds in Ft Knox, KY and you will see the equipment for a modern American Armoured Brigade stored for the Kentuckey National Guard...). If nothing else, the constant flow between the Regular and Reserve worlds would encourage and support the use of high end equipment.
The false economies of buying small numbers of equipment is really the crux of the problems accepting the LAV and the entire "wheeled army" thing. (I am aware of the virtue of track, so please don't start ;D). If enough LAVs were available, then the equipment would be familier; and more people could have the experience to make sensible suggestions for modifications, changes to doctrine and TTPs and so on. A big production run would also invite economies of scale, most of the reason LAVs are so expensive is they are essentially hand built.
This draws a number of threads together, and "perhaps" will stimulate some thinking in the procurment world.....
