That aggro-magnet martyr did a good job of pulling a decent chunk of the zombies off to the side to ease the pressure on his team mates.

non-zero risk of friendly fire by that infantry formation

The front row was not a row, it was a column and a row, and each soldier ahead of the back row was blocking fire from the row behind.   Only viable formation is 2x rows - 1x standing and 1x prone.  There was no need whatever to sacrifice any defender.   Even digging a trench does not change that. 2x rows, no more.  Now if one says the heroes bought time for the base formations to assemble and prepare, that's acceptable, if true, but I can't see the base is not ready and able.

What simulator is this

Did the zombies form a union? Or just decided to to act together?

With unlimited ammunition, all you'd really need are the attack helicopters, no? Why the initial charge away from the blanket of friendly fire protection?

Humans should have limited ammos😂

Situation is risk free for defenders. So there is no interest to watch

What kind of squirmy brain thinks up this crap?
