What plan does Katniss purpose to Gale and why does he ultimately reject the idea?

Katniss proposes a plan to Gale to attack the Capitol by targeting its resources and infrastructure, specifically suggesting they could use explosives to cripple the enemy's supply lines. Gale ultimately rejects the idea because he believes it would cause unnecessary civilian casualties and result in significant collateral damage, which conflicts with his moral beliefs about fighting for freedom without harming innocents. Additionally, he feels that such tactics could compromise their overall mission and values in the rebellion.
