Habits
The spike goes with the team
In one line: Whoever carries the spike stays close to the group that attacks.
Why
No spike, no plant. A spike far from the site, or left where nobody can pick it up, turns a successful execute into a lost round.
How to train it
If you have the spike, watch where the team goes and follow a few meters behind. If you need to do something else, hand it to a teammate instead of dropping it anywhere.
