Having lessened reliability is ok until the 2 that fail are the 2 you had in your truck as you're driving down a hostile road. Or if they won't work in the rain, that's ok until you have to go on patrol in the rain. Or if they won't work in harsh desert conditions... oh, wait.

It's similar to saying that having expendable bullets and grenades is OK until you use the last one while still on patrol. Solution: preparing for it by taking more. Knowing that they're designed to fail/be repaired easily changes the approach. The argument I'm trying to make is that it would be cheaper/lighter/more_versatile to get many expandable droids than to get one robust and universal.

Also, highly-adapted droid != highly-adaptable droid. There is no need for an amphibious droid in Afghanistan, just like one doesn't use the same apparel in all climate zones. As long as interface/principles are the same (like a PC), various versions of it can be used in (almost) any environment without extensive re-training.

While I see where that makes sense, the phrase "The perfect is the enemy of the good" comes to mind. The soldier in the field would probably rather have something like this instead of nothing at all or worse, wait (and die) while something "perfect" is developed.

On the bright side, at least they weren't forbidden from using there own solution.
