For RISK-Are the "reinforcements" at the beginning of your turn chosen from your original set of 36?

Question

Wouldn't everyone choose the higher 10 unit artillery?

Answer 1

Each reinforcement is made up of units.  1st reinforcement is 4 units.  If all you have in your box is 5 and 10 units, then you must make change.  The 5 and 10 units are there just so the board doesn't get too cluttered during play.

Edit:  As for your original question:  Reinforcements are taken from your box and has nothing to do with the amount of units you start with.

Answer 2

I don't think you understand the units in the game. Each player starts with a number of units. The number of units varies withe the number of players. The different types of units can be interchangable, like money. A territory with eight armies can consist of eight infantry or one calvary and three infantry. Get it?
