Well, in your example, there's 2 riptides w/ skyfire and Interceptor, firing S7 ap2 shots around, not to mention a flier. The rest need to snap shot, but sheer weight of firepower should let me ground MCs.
As for the Crisis Suits, doing that requires me to use allies, not formations. That means an HQ, troops, etc. The Formation grants everything Tank Hunter and PE: Marines, and Marines gets Hatred against them.
