Termins "Pin-Up Girls" ir cēlies no tendences, kas tika skaidri uztverta 20. gadsimta 40. un 50. gados Amerikas Savienotajās Valstīs. Tas attiecas uz plakātiem, ko izkāruši vīrieši no dažādu sociālo slāņu (visbiežāk strādnieki vai karavīri, bet ne tikai!) ar īpaši ģērbtām un grimētām sievietēm ar izteiktu erotisku nokrāsu. Piebildīsim, ka, lai arī šie plakāti bija erotiski, tie netika uzskatīti par pornogrāfiju, kas tolaik ASV bija aizliegta. Šīs "Plakātu sievietes", tas ir, Pin-Up Girls, vienmēr bija smaidīgas, valkāja vai nu uzplaiksnītās, brīvās punktveida vai svītrainās kleitas, vai ļoti šauru apakšveļu, vai peldkostīmus. Viņi bieži tika attēloti šortos ar augstu jostasvietu. Protams, Pin-Up Girls tērpi tika pasniegti tā, lai pēc iespējas vairāk atklātu modeļu ķermeni. Piebildīsim, ka arī daudzas Merilinas Monro oficiālās fotogrāfijas ir saglabātas šādā stilā. Izmantotais grims bija arī ļoti skaidrs ar sarkanu lūpu krāsu, kas pasvītrota uz lūpām, un spēcīgām melnām līnijām virs augšējiem plakstiņiem. Jāpiebilst, ka kopš 21. gadsimta sākuma ir manāmi atjaunojusies stila un grima mode Pin-Up Girls garā.
United States Armed Forces ) are currently the most powerful and strongest troops in the world, with an active staff of approximately 1.36 million people and a budget of $ 686 billion in 2018. One of their most important components is the ground army, i.e. the United States Army, in which 476,000 soldiers in the line served in 2017. The most numerous type of army in the ground forces is, of course, infantry - primarily motorized and mechanized. It is theoretically assigned to divisions, but in practice it very often operates within the Brigade Combat Team. Infantry units are divided into the classic Infantry Brigade Combat Team, consisting of, inter alia, three infantry battalions and support units. In 2014, it consisted of about 4,400 people and an infantry brigade on Stryker vehicles (Stryker Brigade Combat Team) based on three motorized infantry battalions and support units. In 2014, it had around 4,500 soldiers and 307 Styker vehicles in various versions. The American infantry also serves in Armored Brigade Combat Team, in companies and mechanized infantry battalions. The main shooting weapons of the American infantryman are the 5.56 mm M16 and M4 rifles. As an interesting fact, it can be said that the private (Private E1) US Army earns about $ 20,200 annually, while the sergeant (Sergeant E5) with 2 years of experience - about $ 28,700. These are basic salaries - without any allowances or bonuses.
