history of Cuba. Many of them worked at a later time at the newly created Centro para la
|
9856_97
|
investigación y desarrollo de la música cubana (CIDMUC), founded in 1978.
|
9856_98
|
From this group we should mention two renowned musicologists that frequently worked in
|
9856_99
|
collaboration with each other: Victoria Elí (b. 1945) and Zoila Gómez (b. 1948). We should also
|
9856_100
|
mention Tamahra Martín (b. 1945), who dedicated two books to the Cuban choral music: “La música
|
9856_101
|
coral en Cuba” (1987) and “Música Coral” (1990).
|
9856_102
|
Two other important musicologists from this generation are: Alberto Alén Pérez (b. 1948) and
|
9856_103
|
Rolando Antonio Pérez Fernández (b. 1947). Alberto Alén applied his extensive knowledge of
|
9856_104
|
psychology and statistics to musical form analysis as well as music pedagogy, in publications such
|
9856_105
|
as: “La forma de las formas musicales” and “Diagnosticar la musicalidad”. Rolando Pérez developed
|
9856_106
|
extensive investigations about Afro-Cuban music and is well known for having documented and
|
9856_107
|
analyzed the process of transition from ternary rhythms to binary rhythms of the Cuban and Latin
|
9856_108
|
American popular music, during the 18th and 19th centuries, in his book: “Proceso de binarización
|
9856_109
|
de los ritmos ternarios africanos en América Latina (1987).”
|
9856_110
|
Olavo Alén (b. 1947) has closely followed the steps of Argeliers León in his studies of Afro-Cuban
|
9856_111
|
music and, most importantly, has elaborated and expanded León's theory of “generic complexes”, in
|
9856_112
|
works such as: “Géneros de la música cubana” from 1976.
|
9856_113
|
Those theories have been strongly refuted by other musicologists such as Leonardo Acosta, who
|
9856_114
|
explains in his article “De los complejos genéricos y otras cuestiones”:
|
9856_115
|
Other members of this Group are renowned musicologists Martha Ezquenazi (1949), Jesús Gómez Cairo
|
9856_116
|
(1949) and Dora Ileana Torres (1956).
|
9856_117
|
Most recently, a group of young Cuban musicologists have earned a well deserved reputation within
|
9856_118
|
the international academic field, due to their solid investigative work. Some of the most prominent
|
9856_119
|
members of this group are: Miriam Escudero Suástegui, Liliana González Moreno, Iván César Morales
|
9856_120
|
Flores and Pablo Alejandro Suárez Marrero.

The LAV III, originally named the Kodiak by the Canadian Army, is the third generation of the Light
|
9857_1
|
Armoured Vehicle (LAV) family of infantry fighting vehicles built by General Dynamics Land Systems
|
9857_2
|
– Canada (GDLS-C), a London, Ontario, based subsidiary of General Dynamics. It is a license-built
|
9857_3
|
version of the Mowag Piranha IIIH. It first entered service in 1999, succeeding the LAV II. It is
|
9857_4
|
the primary mechanized infantry vehicle of both the Canadian Army and the New Zealand Army. It also
|
9857_5
|
forms the basis of the Stryker vehicle used by the U.S. Army and other operators. The Canadian Army
|
9857_6
|
is upgrading its LAV IIIs to the LAV 6 standard.

Development
|
9857_8
|
By July 1991, the Canadian Armed Forces had identified the need to replace their aging fleet of
|
9857_9
|
1960s and 1970s era armoured personnel carriers. As a result, $2.8 billion was earmarked for the
|
9857_10
|
Multi-Role Combat Vehicle (MRCV) project by the sitting Conservative government. The mandate of the
|
9857_11
|
MRCV project was to provide a series of vehicles based on a common chassis which would replace the
|
9857_12
|
M113 armored personnel carrier, Lynx reconnaissance vehicle, Grizzly armoured personnel carrier,
|
9857_13
|
and Bison armoured personnel carrier. The project was, however, deemed unaffordable and cancelled
|
9857_14
|
by March 1992.
|
9857_15
|
By 1994, after the Liberal Party had returned to government, the army was still in need of new
|
9857_16
|
vehicles. As a result, the army embarked on the Light Armoured Vehicle Project, which would adapt
|
9857_17
|
parts of the MRCV Project, and be implemented incrementally to spread out the costs. Also, the
|
9857_18
|
requirement to replace the Bisons was dropped. The first phase of the project saw the selection of
|
9857_19
|
the LAV II Coyote Reconnaissance Vehicle to replace the Lynx.
|
9857_20
|
General Motors Diesel proposed a license-built variant of the 8x8 Mowag Piranha IIIH incorporating
|
9857_21
|
the turret and weapon system of the Coyote. In August 1995, it was announced that GM Diesel (later
|
9857_22
|
renamed GM Defense, and subsequently purchased by General Dynamics Land Systems of London, Ontario)
|
9857_23
|
had been awarded the contract to produce the LAV III which would replace the Grizzly and a large
|
9857_24
|
portion of the M113 armoured personnel carriers.

Future
LAV 6
|
9857_26
|
In October 2011, GDLS-Canada was awarded a contract to upgrade 409 of the service's 651 LAV III
|
9857_27
|
APCs to the LAV 6 standard. Four variants were ordered: an infantry section carrier, a command
|
9857_28
|
post, an observation post and an engineer vehicle. The upgrade was expected to extend the service
|
9857_29
|
life of the vehicle to 2035. In February 2017, the service awarded GDLS-Canada a $404 million
|
9857_30
|
contract to upgrade 141 more LAV IIIs. In August 2019, GDLS-Canada received a four-year, $3 billion
|
9857_31
|
deal to build 360 armoured combat support vehicle variants. The first of these rolled off the
|
9857_32
|
assembly line in May 2021.

Mobility
|
9857_34
|
The LAV III is powered by a Caterpillar 3126 diesel engine developing and can reach speeds above
|
9857_35
|
100 kilometres per hour. The vehicle is fitted with 8x8 drive and also equipped with a central tire
|
9857_36
|
inflation system, which allows it to adjust to different terrain, including off-road. The LAV III
|
9857_37
|
is fitted with a modern anti-locking brake system (ABS). Unlike earlier versions of the LAV, the
|
9857_38
|
LAV III does not have amphibious capabilities.
|
9857_39
|
The LAV III faces the same concerns that most other wheeled military vehicles face. Like all
|
9857_40
|
wheeled armoured vehicles, the LAV III's ground pressure is inherently higher than a tracked
|
9857_41
|
vehicle with a comparable weight. This is because tires will have less surface area in contact with
|
9857_42
|
the ground when compared to a tracked vehicle. Higher ground pressure results in an increased
|
9857_43
|
likelihood of sinking into soft terrain such as mud, snow and sand, leading to the vehicle becoming
|
9857_44
|
stuck. The lower ground pressure and improved traction offered by tracked vehicles also gives them
|
9857_45
|
an advantage over vehicles like the LAV III when it comes to managing slopes, trenches, and other
|
9857_46
|
obstacles.
|
9857_47
|
The LAV III can somewhat compensate for these effects by deflating its tires slightly, meaning that
|
9857_48
|
the surface area in contact with the ground increases, and the ground pressure is slightly lowered.
|
9857_49
|
However, wheels offer several advantages over tracked vehicles, including lower maintenance for
|
9857_50
|
both the vehicle and road infrastructure, quieter movement for improved stealth, greater speed over
|
9857_51
|
good terrain, and higher ground clearance. Wheeled vehicle crews are also more likely to survive
|
9857_52
|
mine or IED attacks than the crew of a similarly armoured tracked vehicle.
|
9857_53
|
The LAV III's turret gives the vehicle a higher centre of gravity than the vehicle was initially
|
9857_54
|
designed for. This has led to concerns that the vehicle is more likely to roll over on uneven
|
9857_55
|
terrain.
|
9857_56
|
While there have been several recorded rollovers (about 16), the most common cause was found to be
|
9857_57
|
unstable terrain, specifically road shoulders unexpectedly giving away beneath the vehicle. The
|
9857_58
|
weight balance of the LAV III is taken into consideration during driver training, largely
|
9857_59
|
mitigating the chances of a rollover.

Protection
|
9857_61
|
The basic armour of the LAV III, covering the Standardization Agreement STANAG 4569 level III,
|
9857_62
|
which provides all-round protection against 7.62×51mm NATO small calibre rounds. A ceramic appliqué
|
9857_63
|
armour (MEXAS) can be added, which protects against 14.5×114mm heavy calibre rounds from 500
|
9857_64
|
meters. In December 2008 the Government of Canada awarded EODC Engineering, Developing and
|
9857_65
|
Licensing Inc. C$81.5 million worth of contracts to provide for add-on-armour kits, modules and
|
9857_66
|
spares for its LAV III wheeled armoured personnel carriers. This armour kit is intended to provide
|
9857_67
|
increased protection against improvised explosive devices (IED), explosively formed penetrators and
|
9857_68
|
30 mm caliber armour piercing rounds. The LAV III can be also fitted with cage armour, which
|
9857_69
|
provides protection against shaped charges. The LAV III is fitted with a nuclear, biological,
|
9857_70
|
chemical (NBC) filtration system accompanied with a GID-3 chemical detector and AN/VDR-2 radiation
|
9857_71
|
detector systems. The LAV III was designed to produce a very low and very compact structure to
|
9857_72
|
minimize radar and IR-signatures. The LAV III also uses heat-absorbing filters to provide temporary
|
9857_73
|
protection against thermal imaging (TIS), image intensifiers and infrared cameras (IR). General
