[Freeciv-Dev] (PR#6458) wishlist: refugees

["Benoit Hudson" <bh@xxxxxxxxxxxxxxxxxxx>]

In warfare, the civilians typically get displaced.  Freeciv has a bit of
that, with enemy units blocking exploitation of a square, and the city
population falling when a defender dies.

However, that is very little problem to the attacker.  In modern
warfare, refugees are a real problem to both sides.  The attacker has
loads of civilians coming his way, with possible enemy units inside, and
he has to feed them -- or shoot them, with concomitant international
outcry.  The defender mostly only has to feed them, but this causes
economic strain and discontent.  Neighbouring countries feed them,
causing a strain in their relations with both warring parties.

Hence, I propose a unit: refugee.  It ignores ZOC, has 1 move, 0
attack/defense.  The closest city pays 1 food per refugee, regardless of
who own it, and suffers 1 unhappiness for every 2 refugees.  The 'b'uild
command functions like a settler's (build a city or add 1 pop), but the
refugee can't do any of the other settler/engineer commands.

In a republic/democracy, killing a refugee is equivalent to 1 military
unit out of town, in every town in the country, for one turn.
Also, reputation takes a hit (matters only in games with AI players).

Not sure how to make neighbours unhappy about refugees.
