Now for the cards that prompted the questions about Tactical Event Cards in the first place,
Experience Level Down and
Experience Level Up.
My own experience in the military backed up by decades of reading combat accounts made these cards two of the first ones I created.
A unit of any organization, no matter what it's reason for being - whether it's a business office, sports team, military organization or any other - has a blend of excellent and poor performers on it. You have the stars of the team and you have the ones that just are just members. 10% of the team will do 90% of the work. These two cards address the situation when that balance changes for whatever reason.
With Experience Level Down you have lost a part of the team/crew that was doing most of the work. This can be to any cause. KN doesn't assume people have to be killed or vehicles totally destroyed to be removed from play. To remove a unit of any sort from play from KN requires that it be combat ineffective for the duration of the combat situation. Which in KN is 30 minutes at the most. What that means with Experience Level Down is one or more of those doing the work are not doing it for the time being.
Experience Level Up is the opposite for the same reasons. Somebody that hadn't been an overly effective member of the team is now doing more than they were.
Often these cards are played on each other. That's because the location on the battlefield that each player wants to influence is often the same. So, a unit may well fluctuate over the span of a scenario with the use of these cards in exactly the same spot. This shows that people are just that. People. With different emotions, incentives and reactions.
A soldier that everybody likes is wounded. (Experience Level Down)
One of his friends responds to that and starts putting out a greater volume of fire. (Experience Level Up)
That soldier then runs out of ammo and is back to being less effective. (Experience Level Down)
An enemy fire team charges forward and another soldier in the group is in position to bring them all under automatic rifle fire. (Experience Level Up)
The enemy fire team takes all that automatic fire unexpectedly and falters in the moment. (Experience Level Down)
KN is a story. The story it tells is written by the random events of the game and the actions the players take with the options they get.
Good Hunting.
