I've been thinking of some new (and much needed) dark barracks troops, and I came up with the Swarm. Swarm would take up 1 troop training space, but when deployed, it will explode into 5 tiny troops, possibly looking like bugs. Example: if you have an army camp that holds 200 troops, and you fill each slot with swarm, when you place them you get 1000 tiny-swarm.
The swarm would each have a very slow movement speed, and each do 1 damage in 3 seconds (possibly more or less) and have 1 health each. This make them powerless alone, but together the only thing that can stop them are bomb traps or mortars.
