See the big bulldozer blade to pass recoil into the earth? This is not a tank, its an artillery gun, a cannon or howitzer (lighter, higher angle), which can cross rough country, keep its crew safe from rifle, machine gun and grenade fire. Probably not the place to be if someone is shooting RPG-7s at you. Its designed to use movement and concealment as armor - observers or a unit in combat calls a fire mission on a location, some number of these weapons aim and fire, and as soon as the last round leaves the barrel, up comes the 'dozer blade and they "displace" far enough from where they fired from that counter-battery fire aimed where the shells came from will find... nothing.

There are two technicalities you have to comprehend of modern artillery, which can still be the queen of battle, if you get stuck in a battle. Number 1: By firing at different angles, the same gun can fire more than one shell which will arrive at the target at the same time. And multiple guns in a battery can coordinate, so that many more than 2 shells can arrive in overlapping patterns of weapons effects at the same moment. Where ever that target area is goes from zero the Hell very quickly, and there's not much that infantry on foot or mounted in vehicles can do to defend themselves, other than scattering.

Number 2, just like snipers watching over infantry or vehicles, the other side's artillery can also be outside of effective small arms range, and deploy radar which will track incoming shells and do the math to find where they came from. Counter battery fire from one artillery to another can be on the way before the first set of shells hit the ground. Which is why the original shooter displaces quickly. And perhaps a shell that homes in on that radar, or monitors which identify and locate the radar as a preemptive target... Time for another try for a negotiated settlement!
