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.
Already after the first experiences of fighting in North Africa at the turn of 1942-1943, the US Army changed the position of the American armored division. From 1943, the full-time armored division consisted of three armored battalions, three mechanized infantry battalions, three artillery battalions and many support units. The exception was the 2nd and 3rd Panzer Divisions, which retained the structure with two armored regiments, three armored battalions each. For this reason, they were often called heavy armored divisions. The armored battalion of other divisions than the 2nd and 3rd consisted of three armored companies - three of medium tanks (M4 Sherman) and one of light tanks (M3 / M5 Stuart). In turn, the mechanized infantry battalion consisted of three infantry companies, a service company and a staff sub-unit. The American armored division also had, like the infantry division, a very strong artillery component, consisting of self-propelled artillery - most often M7 Priest howitzers, of which there were 54 full-time units in the division. In total, the American armored division consisted of, among others: approx. 11,000 men, approx. 250 tanks and approx. 500 M2 / M3 armored personnel carriers.
