Why does types of node in map section have a num_of_soldiers field?

[hbhasker]

I had a question in the Map section

// Different node types have different attributes to take into account in your strategies.
"types": [
    {"name": "node", "points": 0, "number_of_soldiers": 0},
    {"name": "city", "points": 1, "number_of_soldiers": 1}
],

What is the purpose of number_of_soldiers here?

Apologies, this should have read

{"name": "node", "points": 0, "soldiers_per_turn": 0},
