best weapon ever, get a cannon then delete the base sao only the cannon itself is left, then stick someone in it then hold it to the ground and fire.... it turns the guy into a groundsmear
my strategy: each round, get as many gunmen as you can, then use the remaining mony to upgrade your DE. once u get 10k, get a grenade launcher, and watch the carnage as machine gun fire form your gunmen mixes with grenades form you. once u has enough, get the old glory, and gun anyone down who you like, since the gunners will rip the rest to shreds. REMEBER THOUGH big trucks (not the puny fast jeeps* need a nae in them or your castle goes byebye
