Base:
1 centaur or atlas 4 vulture/cents
1 moth 6 vultures / centurions

For each additional trade ship add a wtd and 2 cents/vultures

player taking the escort mission removes one ship from the escort.

If a trade ship is attacked the escort ships attacks the attacking ship to the concurrence from 2 to six ships engaged.

If an escort ship is being attacked some of the escort stand back with him to the concurrence of from 1 to 3 ships max, the rest stays with the voy.

if a player is in the escort and shoots a ship he gets a warning message if he shots again he's out of the escort and considered hostile.

feels free to propose more tuning and adaptation for nation space escorts.
