The Cadillac Escalade is a full-size luxury SUV engineered and manufactured by Cadillac.
 It was Cadillac's first major entry into the popular SUV market.
 The Escalade was introduced for the 1999 model year in response to German and Japanese competitors and to Ford's 1998 release of the Lincoln Navigator.
 The Escalade project went into production only ten months after it was approved.
 The Escalade is built in Arlington, Texas.
 The word "escalade" refers to a siege warfare tactic of scaling defensive walls or ramparts with the aid of ladders or siege towers.
Certified Naturally Grown (CNG), "The Grassroots Alternative to Certified Organic", is a US-based farm assurance program certifying produce, livestock  and apiaries for organic producers who sell locally and directly to their customers.
 CNG was founded in 2002 by organic farmers Kate and Ron Khosla, as a simpler to administer and less expensive alternative to the USDA's National Organic Program (NOP) certification, using a production standard based on the NOP.
 It is operated as a non-profit corporation, headquartered in Brooklyn, New York.
Kodak Retinette is the name of a classic series of cameras manufactured by the Eastman Kodak company.
 They were introduced in 1939 as a less expensive alternative to the Kodak Retina series.
 The first models were of the folding type using bellows and their lenses had three elements as compared to the four element "Tessar" lenses (Greek: Tessera meaning "four") of the Retina series.
 The first non-folding (rigid) variant was introduced in 1954 with the model 022.
 They most often featured Schneider Kreuznach Reomar lenses but, sometimes, Rodenstock Reomar lenses were installed.
 The Rodenstock lenses were based on the original Schneider Kreuznach triplet (three optical element) design.
 Kodak Anastigmat Angénieux lenses were also used especially for the French market.
 Common shutters included Compur–Rapid as well as various Pronto, Vero and Kodak models.
The GMC Denali nameplate is used by GMC on its top-of-the-line trucks and SUVs in the line-up.
 Vehicles with the Denali trim option carry MSRPs (Manufacturer's Suggested Retail Price) up to 47% higher than those of the regular models.
 Prices range from $40,240 for GMC Terrain to (as of 2016) $81,270 for a top-of-the-line Yukon XL Denali.
 The Denali nameplate is often used as an insignia or status symbol, and in particular is popular as a less costly alternative to the Cadillac Escalade.
 The Yukon Denali line typically represents 40% of Yukon sales in both units and dollars.
 In 2013 it sold more than 75,558 units of the Denali brand, which accounted for 20% of GMC's sales, making it one of GM's most successful sub-brands, all done without any advertising or promotion whatsoever.
 As of September 2015, GMC began promoting the Denali brand on television and as the sponsor of the "ESPN Monday Night Football" telecast.
 The Denali is not a luxury car.
The Barrett Model 99 "Big Shot" is a single-shot long-range precision rifle that was first introduced in 1999 by the Barrett Firearms Company as a less expensive alternative to the company's higher-priced offerings.

 This Barrett Firearms Company is known for its .50 caliber rifles, including the M82A1 magazine-fed semi-automatic rifle.
The Cadillac DeVille was originally a trim level and later a separate model produced by Cadillac.
 The first car to bear the name was the 1949 Coupe de Ville, a pillarless two-door hardtop body style with a prestige trim level above that of the Series 62 luxury coupe.
 The last model to be formally known as a DeVille was the 2005 Cadillac DeVille, a full-size sedan, the largest car in the Cadillac model range at the time.
 The next year, the DeVille was officially renamed DTS.
The AV-TM-300 (AVibrás Tatical Missile) or MTC-300 (Míssil Tático de Cruzeiro) is a Brazilian project of cruise missile that is under development by Avibras for the Astros 2020 system.
 Nicknamed "Matador" ("killer"), it is projected to be a less expensive alternative to the American BGM-109 Tomahawk.
 The missile is equipped with a central computer that combines a Ring laser gyroscope, connected to an active GPS navigation device that uninterruptedly supplies positioning information for course correction.
 Apparently there will be also be a naval version called X-300.
A wig is a head covering made from human hair, animal hair, or synthetic fiber.

The GMC Acadia is a mid-size crossover SUV (full-size until 2016) from GMC.
 The first generation GMC Acadia shared the GM Lambda platform with the Chevrolet Traverse, and Buick Enclave.
 The Acadia went on sale in 2006 as a 2007 model in the United States and in Canada.
 The Acadia replaces three of the 7- or 8-seater vehicles on the Pontiac-Buick-GMC dealership network, the mid-size GMC Safari van, the GMC Envoy, and the Pontiac Montana SV6 minivan for the domestic market.
 As of 2009, the Lambda vehicles have replaced the Buick Rainier, Buick Rendezvous, and the Buick Terraza, and then subsequently the GMC Envoy and the Chevrolet TrailBlazer.
 A Denali version of the Acadia debuted in 2010 as a 2011 model.
 In 2016, the second generation Acadia was repositioned as a mid-size crossover utility vehicle (as a 2017 model) in order to compete within the growing mid-size CUV market against the likes of the Ford Edge and Dodge Journey.

 It is renowned for its reliability and ease, but with sophisticated programmability.
