But, police should not be just cannon fodder, as they do have the capability of mounting a good fight under pressure. At such times heroes can emerge.
Not to denigrate the police, but they cannot mount a "good fight" against military units. They aren't equipped or trained to deal with professional armed forces. If a city in the real world is attacked by an infantry division and there are no military units present to defend it, the police - no matter how numerous they may be in that particular city - are not going to be effective in preventing them from seizing that city. Sometimes police forces are seen delaying attacking military units, alongside civil defense forces (this happened in the war in Yugoslavia often, for instance) but they don't have any real hope to do more than slow attackers down. They may have good marksmanship but so do infantrymen and they are equipped much better for the role. They have mortar teams, anti-tank and anti-personnel weapons, combat engineers with demolitions equipment, grenades, rockets, bayonets, white phosphorous, flamethrowers, etc etc etc. Even mustard gas, depending on the time period. Police have pistols and maybe a handful of automatic weapons to go around.
Just to give an example, consider a guy with an assault rifle is holed up in a bungalow and vowing not to go down without a fight. For the police, this is a major thing; half the department will be down there, they'll have the best men and their most trained people on the case. For most policemen it would be a once in a lifetime experience. SWAT handle this stuff more often, but how much of a police force consists of SWAT? 1% maybe? For the infantry in a wartime situation, he's no more than a pest and far from the most threatening thing they'll encounter. "Williams, go toss a grenade in that window, we have to get moving" sort of thing. They are equipped and trained for entirely different sorts of combat and entirely different rules of engagement.
