Here is my list. Not optimal as its restricted by what I own. I especially want to get some commandos and an express team. Stryker 3 Gravediggers -Sylys Wyshnalyrr -Ol' Rowdy -Grenadier -Sentinel Captain Finn(free) Hitch Patrol Dog Buster (free) Master Gunner Rangers Cannon Crew Trencher Infantry -3x Rifle Grenades -Officer and Sniper Aiyana and Holt -Murdoch
I've actually had a lot of success with this list and swapping through multiple casters. Caine1 and Jakes2 particularly like it.
How do the Rangers do for you? I like the unit, but rarely include them because they don't benefit from all the ingrained Trencher synergy
Honestly they are great in some games and little more than road bumps in others. I often find that def 14 with prowl and a decent gun comes into play more often than marked target. I tend to stagger them on a flank and use them to slow down the opponent but in probably 1/4 games that extra 2 to hit really comes in handy for the grenadier and the cannon crew.
