tips for hard badge: 1) the colonel badge upgrades are a necessity. 2) early on, concentrate on building your team, especially when driving around (you won't get far). 3) keep an eye on your team's health, and try to distribute damage accordingly. 4) i never used Heroic Dash, just because i would always end up in a worse position than the one I was trying to escape and dying shortly after. 5) keep trying! the 'waves' repeat themselves, so you'll get the hang of things.
