《哥斯拉》中高空跳傘的士兵腳上的紅煙有啥作用？

12-09

那是跳傘方式的一種——高跳低開，這種方式可以盡量減少預留空中的時間減少因風速而造成的遠離目標地點和被敵方發現的概率，而腿上綁照明彈是為了方便在夜間高跳低開時相互之間觀察對方與自己的距離防止在下降過程中發生碰撞或更嚴重開傘時被繞，以及在先抵達地面的隊員便於躲開將要抵達地面的其他人，減少夜間跳傘時的非戰鬥減員。我軍空降部隊在夜間訓練時會在身上綁一個手電筒，還有些其他國家部隊在夜間跳傘也有在腿上套一個熒光條（通常是紅色，黃色）。有興趣自己可以上網查一下夜間跳傘的圖片和視頻看看。
我軍空降部隊這是把手電筒捆腰上了，登機前檢查裝備

約旦空降兵頭盔上帶著熒光棒

胸前也有

Quora上有關於這個問題的回復，原文如下：

There was an article in Business Insider with an explanation from a military advisor:

When we spoke with the film"s military technical adviser, retired Sgt. Maj. James Dever, he explained how something as small as red flares could be effective against something as big as Godzilla.

"The use of the red flares was never to attack the creature," said Dever. "It was used to divert the creature ... to distract him."

The flares — and red smoke — divert the monster"s attention long enough for the military to use its more powerful artillery or even clear the area.

In real life, the military uses smoke and flares in similar ways.

Smoke can be used to create smoke screens for cover and the different colors of smoke can signify enemy targets and identify landing areas for aircraft.

大意是（英文不好），軍方顧問說，煙霧主要是分散打怪物的注意力以爭取更多調度時間，不是為了直接攻擊它。在現實戰略中也有類似的做法，用來定位。

大家都沒有說為什麼綁紅色照明彈好不。。
由於是晚上跳halo，需要標註隊友位置以防纏繞等事故，所以需要標記。
由於有emp，無法用夜視儀，求生燈，ir也沒有用處。所以需要綁紅色照明彈。

視覺效果
背景本來就暗，沒有紅煙的參照，怎麼看得出有幾個黑點在運動呢

除了顯得酷應該沒別的用了……

腳上綁東西是因為文藝跳傘要擺POSE，不然稍微遠點就看不見了

而HALO是強調隱蔽性的，沒必要這樣干。

有高人推薦答案如下：There was an article in Business Insider with an explanation from a military advisor:

我的英文也不好，但是我看了樓上轉載的Quora問答，覺得英文原文是說得夏威夷那段軍人們從樓上朝天上設計照明彈，看到了一部分哥斯拉吧！ @Evelyn Tong你這個回答跟題主說得高跳低開是沒有聯繫的。尤其是 @lee leo 同樣的回答居然還有人點贊，答歪了誒！

你看張家界的低空跳傘比賽時，腳上，背包上都有這東西，私以為那是為了好看的。
