Currently the DE impalers on ships read as if they do 6 troop damage.

Upon testing them I noticed that they do not. Here a battleship launched 3 impalers and did 9 troop damage while a light cruiser launched 1 impaler and did 3 troop damage.

Upon launching the impalers, the impaler from the DE cruiser and light cruiser launch in a damaged state.

Also unsure if this is a bug or was intentional, but the light cruiser and cruiser both only launch 1. Most likely it is supposed to launch 1 instead of 2.

With the beta patch, impalers are now doing the correct amount of troop damage but are still coming out damaged in light cruisers and cruisers unlike the battleship variant.
