"One of those buildings specifically designed to withstand a siege?"
"Right. Bear with me but what if we... found them outside?"
"We don't dig any trenches?"
"Love where your head's at!"
"Think we should hold them in reserve? Have them ride in on a flank once the zombies are committed?"
"Better idea: We just throw them away in a useless charge."
"You're hittin' gold here! Gold!"
"We're not besieging anything."
"Still, we have them."
"Okay, use them, but immediately stop when the cavalry's engaged. Then never use them again, even after the cavalry's inevitably wiped out."
"What about them?"
"Well, they're used to fighting in a phalanx."
"Right."
"What if we broke that phalanx up? Made sure they couldn't lock shields?"
"Ooo, that's good! They'll be useless!"
"Gods, who invited the narc?"
"Hang on... that sounds like a good idea."
"Wait, we dig it behind the lines."
"That's good."
"And we don't light it until after half our people are dead."
"Perfect!"
"Of course."
"Let's make sure we don't have any of that."
"Good plan. Gotta be sporting."
"Someone remove the narc!"
"Sounds too effective. What's option B?"
"Six dudes with bows."
"...well, you know where my head's at."
"Good point. Could you imagine if we'd put them at chokepoints and just had them roast whatever was funneled in there?"
"Ha! We'd win in seconds."
"Nah. Better let the dracolich do what it likes."
"Maybe. Why?"
"Well, we have the perfect bait. You think we should plan around that?"
"Gods no. Make that an afterthought. At best."
"Just like we drew it up."
