Reinforcements - StephenE/DevoLAN GitHub Wiki

At the start of the reinforcements round, all players are given a pool of troops to deploy as follows:

• 1 for every three regions owned. If you own less than 9 regions, you still earn 3 troops
• A bonus for each continent [7 troops for Asia, 5 troops for Europe or North America, 3 troops for Africa and 2 armies for South America or Australia]

In addition, players can choose to trade in any cards they've collected for bonus troops. They can either turn in three of a kind or a set of three. If a player has 5 or more cards, they must turn in cards until they have fewer than 5 cards. For the first set of cards you turned in, they receive 4 troops; 6 for the second; 8 for the third and so on. If the player turns in a card for a region they own, that region automatically gains 2 bonus troops.

There is no limit on how many troops can be placed in a given region.
