Start the run on Three Mines ’Round – Military Only (Medium) by placing Quincy. His early reliability helps stabilize the first waves while you build a powerful long-range setup.
- Move to the upper-left tent area and place two Sniper Monkeys. Set the first Sniper’s targeting to Strong and upgrade it along Path 1 once to make it 1-0-0 for steady early damage.
- Upgrade the second Sniper along Path 2 and Path 3, turning it into a 0-2-4 Full Auto Rifle for rapid-fire bloon clearing.
- Next, upgrade your first Sniper further along Path 1 and Path 2, turning it into a 3-2-0, then return to the second Sniper and finish its Path 3 upgrade to transform it into the powerful Elite Defender.
Finally, complete the first Sniper by upgrading it to 4-2-0, giving your defense consistent high-pierce coverage. - Add one more Sniper Monkey and upgrade it to 2-4-0, rounding out your military lineup with excellent single-target and general-purpose damage.
This simple, long-range defense is more than enough to defeat Military Only on Medium—victory guaranteed!
