DW's coverage of same: ''After a training exercise involving 18 state-of-the-art Puma infantry fighting vehicles, not a single one was left operational''

Can't help but notice that no timeframe was published. How long was the exercise? A month? A week? A day?

In any-case, whether the problems plaguing the Puma are fixable by retrofitting, or if a new design all together is necessary, is a real question with some effects to note.

After all, replacing electronic parts is completely different from replacing key mechanical systems or even sections of the hull.

It all depends on test's reports.

FYI, the way Germany works is that it has a very high threshold for "combat ready". Does "technical malfunction" include things like a headset breaking, or a radio link failing to sync up or other things?

It's probable that in an actual conflict, Germany would be able to safely and reasonably field more vehicles than what they usually list as "Combat Ready" because maybe the tail-light doesn't really matter if you have to actually defend your land.

Seems like sabotage. Germany can surely engineer a functioning tank.
