If you don't train, you won't be able to fight.
I know, I know... But 5 deaths in one month is rather unusual (at least by Polish army standards).
The Polish army doesn't have to train.
I'm sure Trump would disagree lol
Deaths frequently happen in the USA services.
I know. Apparently more US soldiers die in training than in combat. But in the US they also do "safety reviews" if "too many" die in a short time span:

When my brother went into military this was one of the things I was afraid of most - that he will die or get maimed in one of those accidents.
