Other forms: regrouped, regrouping, regroups
To regroup is to gather and reorganise after a setback. Regroup and try again, let us regroup, the team regrouped.
The military sense is literal — pulling back to reorganise before continuing — and the everyday one is a meeting or a pause to work out what to do next, which is now much the commoner use. Let us regroup is standard office language for stopping a conversation that is going nowhere. Note that regroup implies the setback was temporary, which is why it is a hopeful word.
