This is a small exploit which makes 
your missions MUCH easier.
 
First, save your game, then end your 
mission. Return to the mission screen,
and click Change Gear. You MUST change
at least one item of gear for this to 
work. Accept your gear, click once on 
your save game, and hit Start Mission.
You will be returned to your saved game
with the new gear you chose, a fresh 
(full) load of ammunition, and full 
health.
 
This exploit is terrific for missions 
that combine long-range combat with
tunnels or buildings.
