I am very impressed with this unit. I've built myself a rather complex scenario using the Teturkhan scenario map that's got about 300 units in it or so, with a specialized units for each civ to make it more historically accurate (i.e. the Americans get the M1A1, which is the second most powerful tank in the game; the English get the Challenger, which is the most powerful tank; the Chinese get the T-80, soon to be replaced by Mr. lav_dav's Chinese MBT, which is, well, not all that great). However, I've had trouble finding a good set of self-propelled artillery that all civs can use. I had been using the Wespe, but I've needed something for it to upgrade to. I'm thinking I'll use the 70-II as a modern SP artillery unit, while the Chinese will get the 70-1T as a special unit. Sound good?
Once again, a most splendid unit.
