DOT ndizofunika kwambiri

Pambuyo pa nkhondo yayikulu yokonda dziko ladziko kwa zaka zitatu kapena makumi anai, anthu akumbukira nkhondo yapitayi inali yatsopano. Ankhondo akale ankawoneka ngati okalamba kukhala anyamata, koma anali ndi zaka makumi anayi ndi makumi asanu zokha, ndipo amatha kunena zomwe zinachitikira zaka zovutazo m'chinenero chophweka ndi chomveka. Mwana aliyense wa sukulu ankadziwa za kugwiritsidwa ntchito kwa Alexander Matrosov, yemwe anatseka kugunda kwa mfuti yake ndi thupi lake, motero amathandiza omenyana ake kuti agonjetse udindo wa mdani yemwe anaphimba DOT. Kulimbikitsidwa kumeneku kunali chopinga chachikulu kwa asilikali omwe akupita patsogolo.

Mitundu ya mipanda yamtunda

Mzinda wamakoma ndi waukulu komanso osakhalitsa. Mwachitsanzo, zida kapena bunkers zimamangidwa mofulumira, kuchokera ku zipangizo zopangidwa bwino kapena ndi kuwonjezera nkhuni zinazake zomwe zimabweretsa. Ulemu wawo umakhala mukuti maonekedwe a mfundo izi nthawi zambiri amadabwa kwa mdani wamkulu, pakuchitika, ndithudi, kuti ntchitoyi inkachitika ndi chinsinsi chokwanira. Mtundu wachiwiri wamalinga ndi konkire yamphamvu ndi zowonjezeredwa zomwe zimatha kupirira kuzungulira (nthawi zina zozungulira) kwa nthawi yaitali, kumangiriza mphamvu za adani. Kuti iwo akhale ovuta kuwombera, mfundo zowotchera zikuphatikizidwa kukhala chitetezo - chitetezo. Chigawo cha mzerewu ndi DOT. Chidule ichi chikuimira "nthawi yotentha moto". MPT yomwe yatchulidwayo imasiyana ndi izi polemba makalata akuti "O" (moto) ndi "T" (dot), palinso "D" (matabwa) ndi "Z" (nthaka), kutanthauza zipangizo zopangira. Nyumba zinamangidwa ndi zida ndi konkire.

Mfundo Yopereka Chitetezo

Zida zam'tsogolo zatha nkhondo ya 1914-1918 idawonedwa ndi akuluakulu a mayiko ambiri monga njira yodalirika yochotsera nkhanza. Chikhalidwe cha nkhanza zomwe zimachitika ku Western Front chinachititsa kuti zikhulupilire kuti njira yaikulu ya mikangano yomwe ikubwera idzakhala kuthera kwachuma kwa mdani. Chinthu chokhacho chinali kupambana kwa Brusilov, pamene asilikali a Russia anatha kupyola pakati pa dziko lonse la Austria (1915). Koma mlanduwu unkawoneka kuti ndi wapadera ndipo sunaganizidwe, koma pachabe. Maganizo anali olakwika.

Kale mu 1939, asilikali a Red Red adachita zomwe zinkawoneka zosatheka - anatenga Mannerheim Line. Panthawi imodzimodziyo, olamulira athu ndi asilikali adziwa kuti DOT ndi chiyani. M'nkhondo, chirichonse chimagwiritsidwa ntchito potetezera, chimene achibwibwi angagwire "- chigwa, mtsinje, nyumba kapena mabwinja ake. Ku Finland, zipangizo zamakono zili pafupi.

Malo ndi malo oteteza

Mzere wa Mannerheim unkawonekeratu kuti sungatheke. Zingatheke kupeŵa, ndipo ndizosatheka kuzigwira. Ngakhale tsopano, palibe gulu la mtendere (popanda kugwiritsa ntchito zida za nyukiliya) lingathe kuthana ndi ntchitoyi. Ajeremani anadutsa Mzere wa Maginot mu 1940, sakanakhoza kuugonjetsa pamphumi. Mmodzi mwa malo amphamvu kwambiri okhala ndi mipanda yolimba kwambiri akhoza kutetezedwa kwa nthawi yaitali kwambiri. DOT iliyonse sikuti imangotentha moto, koma malo osungirako zinthu zowonongeka, kuphatikizapo malo opumula, ukhondo, kudya ndi kuphika, ndipo, ndithudi, zida zazikulu zogwiritsira ntchito zida zankhondo. Zomwezo zinamangidwa ndi Japanese ku Southern Sakhalin, ndi USSR kudutsa malire a Chineina. Tanthauzo lenileni la liwu la DOT limatanthawuza kuti lidzatha nthawi yaitali, motero likhale lotetezeka.

Bunkers zamakono

Mkhalidwe wa nkhondo yowonongeka monga mikangano yamakono yamakono, zingawoneke kuti zida zowononga nthawi yaitali ngati zida zotetezera zatha. Inde, pakufika kwa kuthekera kwa mphamvu zowononga amphibious, mphamvu zowonongeka zothandizira moto kwa anthu othawa, kusokoneza DOT yachikale si ntchito yovuta. Komabe, chitetezo chimakonzedwanso. Ngakhale kumayambiriro kwa zaka za m'ma 1960, nyumba za Gorchak zinamangidwa, ndipo kenako - VZU-100, zomwe zimatha kusunga nkhondo ngakhale ngati zida za nyukiliya zikugwedezeka m'deralo. Izi zimathandizidwa ndi kuya kwakukulu mu nthaka, mpweya wabwino "ndi kutayira" komanso zipangizo zamakono zoteteza moto. Ma DOT adakali m'gulu, ndipo kudzipatulira kwawo sikukuwonetseratu.
