I can understand not using Spektrs, because they're so damned expensive (though everything but the MSR and basic combi are worth what you pay for) but not using Clipsos? Those are one of the best units Tohaa has! I mean, I'm biased, coming from Ariadna and all, but camo infiltrators can be game changers (and game winners, for that matter.) Try bringing the Spektr next time, especially the KHD. Sure, he's not an Interventor, but I'm pretty sure that the only hacker in the game that's better than Interventors is Mary Problems, and even that's debatable. The KHD Spektr is WIP 14, and has the advantage of surprise shot coming out of TO camo. Super solid.
Also, grenades are [big bad swear word]ing awesome, especially on warbands. They can make great direct fire, FtF weapons, too. Some of them are pretty situational (the Igao's stun grenades, for example... probably only of value against multiple wound models with total immunity, because stun ammo is exotic, hence Loup Garous carrying flash grenades.) I have used grenades of all types to good effect in the past; linked LGLs are awesome, though perhaps not in triads because all you get is the +1 burst that gets negated by spec fire anyway. I've used Dog Warrior grenades to force a FtF roll if someone tries to dodge my chain rifles. And yeah, E/M grenades are stupid good, especially if there's no engineer handy. Grenades of various sorts don't seem to be commonly included in high-cost, low model count factions, though; Tunguska only has the one source of smoke grenades on Perseus and that's it, am I right?
But yeah, try the infiltrators & FD guys. And with MI getting it in ITS X, try a Grenzer haris; take a spitfire and then a forward observer to push buttons. A B5 spitfire escorting a specialist and deploying 16" up the board is nothing to sniff at. Rambo runs with Krizas and Hollow Men are great, but if they lose a gunfight, you've lost the tip of your spear, and since you'll probably not have both of them due to their expense, you're kinda up [big bad swear word] creek at that point.
