How do you see it?

Just a quick reply: in modern warfare there are two methods of attack that do not involve assault by the firing units: attack by fire and support by fire. Attack by fire is where a unit establishes themselves and fires on an objective without actually advancing. In a support by fire a unit does the same but it is supporting another unit that is advancing to and will eventually assault. Maybe that helps(?). In PzC and MC, a unit firing without assault is basically conducting an attack by fire.
