Tank mine strategy

This strategy is used in a military context to "take-out" tanks on a battlefield:

• Slow down a tank with a tank mine (small device doesn't destroy tank in total)
  
• Slow tank is easier target and can be taken out with a bazooka.

In other words: some times it can be useful to use a catalyst or an intermediate step to reach your goal. One tool might not be useful in a givin situation but maybe one can change the setting and then apply adequate tools.
