Renegade Ops agents can opt to bolster their fleet through The Vehicle Pack, which adds two new heroes to your ranks: Crystal and Blazemo. Each has their own unique set of weapons and abilities. They can be yours for 240 MS Points ($2.99).
The other option is codenamed Coldstrike Campaign, and adds three new war zones to the Renegade Ops mission agenda. Accepting this mission will require you to produce 400 MS Points ($5) for the cause -- the enemy is entrenched in the icy tundra and is employing new enemy variants such as the Golem, a large factory that pumps out low-flying aerial units. It's much different from our original intel, which showed the enemy enlisting the aid of Jewish sorcerers.
Relax, sorcerers do not exist.
