Mine Clearance: What's the best way?

[Mr Grumpy]

I always thought the engine did take at least take quality into a account and fatigue....don't know about numbers.

Strangely no, the only advantage to higher quality is the fact your engineer unit is less likely to disrupt when fired upon.

So a 10 man E quality unit will clear a 1 hex of mines at the same speed as a 1000 man A quality unit.

I have no idea why this is the case? At least when you lay mines a unit with a strength of 100+ has more chance of success than a unit with 99 men, but again unit quality has no effect. ;)
