I think it is just a typo in your code if you change the line (replace yourSchema with schema)

var Tank = mongoose.model('Tank', yourSchema);

to

var Tank = mongoose.model('Tank', schema);

As the definition is for the var schema

var schema = new mongoose.Schema({ name: 'string', size: 'string' });

I ran the script with the typo corrected and it outputted two IDs.
