3 tactical questions

[brucemcl777]

Here's 3 new questions that have come up and I can't find anything in the manual about them.

1/ Does anyone understand the difference if any between artillery doing its regular fire on an enemy and bombard? Or is it the same thing?

2/ I had taken over an enemy airbase close to the front lines and parked 4 squadrons in it all heavily damaged and did not have the points to bring them back - meanwhile some kind of long range (artillery?) destroyed the base. I think all 4 squadrons were also lost - is that you fellas understanding of how it works as well? In which case I should have launched while weak but refueled or went to a base farther back in my territory.

3/ How do I put a unit to sleep so the zzzz's flow off it - I've done it but only by accident and don't know how exactly?
