Infantry guns were used in the direct firle role exclusively. Sort of a poor man's Assault gun. The differences between the two (infantry guns and assault guns) is the tracked chassis of the assault gun. Employment was the same. Now, to get further confusing, in the REGULAR artillery, there were *Field* guns. When discussing field guns, infantry guns, or AT guns, it is important to specify which type. you see, all *guns* operate much the same, whereas *Howitzers* operate differently. A gun is characterised by a high muzzle velocity and reasonably flat trajectory. This permits VERY long range, accurate fire. Cannon on tanks are also guns. Unfortunately, since guns have a very flat trajectory, they cannot normally bring fire on targets that ae, say, behind a hill. Enter the Howitzer. Howitzers use a higher angle of fire, at long range they are often firing shells as high into the air as they are downrange (a shoot that sends a shell 10,000 yards downrange will often also send that shell 10,000 yards into the air, in a parabolic arc). Because of this, howitzers can *also* accomplish the most desired kind of barrage - the ToT, or Time on Target. A ToT is where every shell from a firing battery impacts in a short, 1-5 second, period of time. This maximises the suppression and damage on the target. Essentially, in a firing battery, (we'll use US artillery for this example) each piece is given the target point and so much time to make the individual settings for the piece. Since the howitzers are not all on the same point on the earth, each one must caculate it's own firing beraing, barrel angle, and charge. Most Howitzers use bags of propellant so that they can vary the charge when firing at different ranges. When firing, each howitzer will fire three rounds in rapid succession, so if there are 9 pieces in the battery, 27 shells hit the beaten zone. ALL in 1-5 seconds of each other. Just as nearly all howitzers use propellant bags, most guns use fixed charges where the shell is attached to a brass casing full of propellant, much like an immense rifle bullet. this is typically true for AT Guns, Infantry Guns, and Field Guns. Does that help clear up the misunderstanding?
