根據《軍事醫學雜誌》的一篇研究（https://voenmed.ric.mil.ru/upload/site229/F9Ofiaaq76.pdf），在塹壕戰中，超過75%的傷亡是由無人機造成的。該研究由軍醫發表，引用了對5813名在作戰行動非活躍（陣地）階段受傷的俄羅斯軍人的調查統計資料。根據這些資料：
75.5%的傷害是由FPV無人機投擲和打擊造成的； 20.5%的傷害是由炮兵彈藥造成的； 僅有4%的傷害來自小型武器
將傷員送至提供合格外科護理（QSC）階段的平均時間為14.5小時，這也受到無人機積極使用的影響，無人機影響了醫療撤離的各個階段以及傷員撤離路線。
大多數傷害發生在四肢，佔58.2%，大部分傷病被歸類為輕傷，佔73.3%。
與作戰行動的活躍階段不同，在陣地戰中，輕傷數量顯著增加，而重傷和穿透性傷害的數量減少。此外，明顯地從接觸線組織撤離重傷員是非常困難的，這會影響重傷員在衛生減員總體結構中的佔比下降（說得直白些，這些傷員往往等不到救援就會死亡）。（註：衛生減員（Sanitary Losses）指的是有醫療需求的戰鬥減員）
另一個特點是，頭部和胸部的傷害大多不嚴重（頭部主要是未受保護的面部區域受損，胸部則是瘀傷和閉合性肋骨骨折）。結論很簡單——穿上SIBZ（個人防護裝備）！
在當前條件下，幾乎一半的輕傷員無需離開軍事區域即可返回崗位。其餘56.7%的傷員中，約有一半在附近部署的輕傷員醫院接受救助，僅有四分之一（25%）的傷員被送往後方治療。
因此，與活躍階段相比，非活躍（陣地）階段的特點是嚴重、極重和穿透性傷害的比例減少，但輕傷的頻率增加，且將傷員送至接受合格外科護理階段的時間延長。
More than 75% of casualties in trench warfare are caused by drones – Military Medical Journal.
The study (https://voenmed.ric.mil.ru/upload/site229/F9Ofiaaq76.pdf) by military doctors, published in the pages of the magazine, cites statistics from a survey of 5813 Russian servicemen wounded in the inactive (positional) phase of combat operations. According to these data:
▪️75.5% of injuries were caused by FPV drone drops and hits ;
▪️ 20.5% of injuries were caused by artillery ammunition ;
▪️and only 4% of injuries were received from small arms .
The average time for delivering a wounded person to the stage of providing qualified surgical care (QSC) was 14.5 hours , which was also influenced by the active use of drones, which affect the stages of medical evacuation and the evacuation routes for the wounded.
Most of the injuries were to the extremities – 58.2%, the majority of injuries were classified as minor – 73.3%.
Unlike the active stage of combat operations, in positional battles the number of light wounds increases significantly and the number of severe and penetrating injuries decreases . In addition, there are obvious difficulties in organizing the evacuation of seriously wounded from the contact line, which affects the reduction of their share in the overall structure of sanitary losses (they die without waiting for help, to put it simply) .
Another feature – head and chest wounds are mostly not serious (in the case of the head, damage to the unprotected facial area, in the case of the chest, bruises and closed rib fractures). The conclusion is simple – wear SIBZ !
Under current conditions, almost half of the lightly wounded return to duty without leaving the military area. Of the remaining 56.7%, about half receive assistance in hospitals for the lightly wounded deployed nearby, and only a quarter (25%) of the entire flow are sent to the rear for treatment.
Thus, the inactive (positional) phase, in contrast to the active one, is characterized by a decrease in the proportion of severe, extremely severe and penetrating wounds, but an increase in the frequency of minor wounds and an increase in the time it takes to deliver the wounded to the stage of receiving qualified surgical care.
