Does the bold「に」indicate reason or cause? If so, why isn’t「で」used? The verbs
after「に」(in the sense of _because_ ) should be those describing psychological
or physiological reactions. So how should I understand this bold「に」in this
particular case?

question
grammar particle-に
Understanding に in 砲撃に
It is an untypical usage of に. From the context, I guess this is a somewhat
stretched application of a branch of definition similar to [this
one](https://japanese.stackexchange.com/q/64954/7810). So you can probably use
～のために here.

> **７** 動作・作用の原因・理由・きっかけとなるものを示す。…のために。…によって。「あまりのうれしさ―泣き出す」「退職金をもとで―商売を始める」
> ([source](https://dictionary.goo.ne.jp/word/%E3%81%AB/#jn-166083))

The author's usage of this に is terse and certainly rhetorical, but a little
forced. A several words later it also says 叩き割るのに where I'd use 叩き割っても
instead. Perhaps the author prefers such type of construction.

> 至近距離で炸裂した近接信管の砲撃に砲弾片がコクピットに飛びこみ…  
>  "A shell with proximity fuze exploded in no distance so that a shrapnel
