Available since Ch.3, this is a light little skirmish with light rewards.
However it is also a easy map for unlocking potentials.

[00:22 CP1, Any] Go east following dirt path, and deal with the leader scout.
[00:51 CP2, Scout] Go southwest pass the hill, then run to the bridge and blow leader scout.
[01:27 CP3, Scout] Cross the bridge, shot down base scout, occupy base.
[01:59 Appraisal, 2180 exp + 1700 dct]

If you bring all leaders, you actually have 1 CP for each enemy.
That means you can wipe them all if you want to.

As for potentials, you can unlock personal potentials ("P") that says "-" instead of a diagonal line, for non-leaders of Squad 7.
There are many detailed guides on the web, so here is a short version.

Deploy these soldiers - remember to bring a scout - plus an weak unit.
Move that unit ahead and let him/her drops to 0 HP.
Send a unit with locked potential to run up and call medic, then also let him/her drops.
Rinse and repeat.  Leave 2 CP for the scout.
Every soldiers that called medic, plus the scout, would be heroic enough.
Next time you visit Castlefront St., their potentials will be unlocked.

Not all personal potentials are good.  Unlock at your own risk!
