The safest place to be in combat is somewhere else, barring that then be on the winning side. The winner never has defend against war crimes. All five second fuses last 3 seconds. The simple things are always hard. The easy way is always mined If you are short of everything except enemy, you are in combat.
Incoming fire has the right of way.
When you have finished securing an area, don't forget to tell the enemy. No combat ready unit has ever passed inspection. Things that must go together to work, usually can't be shipped together. Anything you do can get you killed - including nothing. The only thing more accurate than incoming enemy fire is incoming friendly fire.
