Got this idea while reading a thread about HMS Dreadnought's shell vs 'Mech armor. These are the 10 to 18 inch guns (10, 12, 14, 16, 18) used by naval warships in the early 20th Century. I mainly extrapolated some from the assumption that the Long Tom artillery piece is roughly equal to an 8 inch naval gun. The following are nowhere near exhaustive or definitive, being merely abstractions of real world weapons. Also, I decided to keep them somewhat close to the Cruise Missiles in TacOps. Ranges of the rifles are about half that of real world maximum ranges for balance purposes vs Cruise Missiles. Lastly, since these are not technically artillery pieces and need to fit onto large naval vessels, space taken up is roughly about 40% of weight. If any changes are felt needed, please let me know.

Naturally, I couldn't, in good conscience, post these without doing alternative ammo as well.

The damage modifier for armor piercing ammo is due to game balance vs armor used by 'Mechs, combat vehicles and fighters. This is counterbalanced by the special ammo weighing the same as normal. Otherwise, treat a hit like an AP round from an AC/20.
Well, if there are any problems with these, please let me know. I am open to changing things around some.
Finally, I do not have battle values for these as I do no know how to calc those out.
Peace.
