The four requirements of infantry...

[Mike Abberton]

Regarding rest, when I need to advance across an open area from one bit of cover to another, I like to walk the first half and advance (or run) the second half.

I do this because if someone has a cover arc on the open area, it is more likely that it starts in "their" half of no man's land. That way, my guys are still good and rested when they start moving quickly and when they start taking fire, they seem to be more likely to keep going that way.
