NYC88mm said:actually, the chinese 155mm GUn-HOWtizer is both direct fire and indirect, its very capable of kiling a tank if directed and aimed wiht a laser range finder
btw, the chinese has a couple thousand of these toys planned for thenext 5 years[/img]
155mm with different AT ammunitions is enough to penetrate and gives a hard punch without penetration but think about which one is going to win, a modern MBT or an immobile arty piece? Howitzer may shoot once and due to immobility stays on field as a sitting duck. When spotted, it will be an easy target for a modern MBT. Howitzers are also quite bad to take punishment from enemy indirect fire. Guns agains tanks belong to times of WW1 and 2.
Of course if you got guns enough, just put them all line and engage incoming tanks. Don't care about casualties because gun is only a gun purchased with money and the crew is only a few pieces of meat easily replaced.
