Pali zinthu zambiri zomwe zatsimikizira kuti kugwiritsa ntchito ma vest osalowa zipolopolo kungachepetse bwino kuvulala kwa asilikali pankhondo. Kuphatikiza apo, m'maiko ena, chitetezo cha anthu ndi choipa ndipo pali zochitika zambiri zachiwawa. Kudziteteza ku kuvulala kwa munthu ndikofunikira kwa apolisi komanso nzika wamba. Pachifukwa ichi, mayiko ambiri ayamba kufufuza zinthu zosalowa zipolopolo ndi ma vest kwa nthawi yayitali. Pa Nkhondo Yoyamba Yapadziko Lonse, mbale zachitsulo zinagwiritsidwa ntchito poteteza anthu, ndipo pambuyo pake kafukufuku adachitika pakugwiritsa ntchito zitsulo monga aluminiyamu ndi titaniyamu. Komabe, pankhondo, asilikali ayenera kusunga kuyenda. Chifukwa cha makulidwe a chitsulocho komanso magwiridwe ake osalowa zipolopolo, anthu anayamba kuphunzira zinthu zina kuti apeze zotsatira zabwino zoteteza zipolopolo. Chifukwa chake, pambuyo pa Nkhondo Yachiwiri Yapadziko Lonse, ma vest osalowa zipolopolo anakhala zovala zoteteza ku zipolopolo zosiyanasiyana. Pakadali pano, zakhala zida zofunika kwambiri zotetezera asilikali ndi apolisi. Nthawi yomweyo, kupanga zinthu zosiyanasiyana zosalowa zipolopolo kumayamikiridwa kwambiri ndipo kukukula mwachangu m'maiko padziko lonse lapansi. Mitundu yosiyanasiyana yatsopano ya zovala zosalowa zipolopolo ikuphunziridwa nthawi zonse ndikupangidwa bwino.

Pakadali pano, majekete osapsa zipolopolo amagwiritsidwa ntchito makamaka pa mitundu iwiri ya chitetezo: Chimodzi ndi zipolopolo zochokera ku mfuti ndi mfuti, ndipo china ndi zidutswa za kuphulika.
