This is a Republic Commando squad that I built for 100 pt. games:

Figure Name Cost Hits Def. Atk. Dmg.
Republic Commando - Boss 19 30 17 9 20
Republic Commando - Boss 19 30 17 9 20
Republic Commando - Scorch 16 30 17 9 20
Republic Commando - Scorch 16 30 17 9 20
Republic Commando Training Sergeant 30 30 15 10 20

Total Deployment Cost: 100

Total HP: 150 | HP/Cost ratio: 1.5:1

The strategy is to run your Scorches out on the board and hit range with grenades until you can get close enough to close in. Use the Boss ability to make extra attacks. Don't forget to use Delta Shields granted from your Republic Commando Training Sergeant!

One of the guys in our group had the same idea and ran it against my Mandalorian Squad. He was able to close in on my Gunslingers so they couldn't use evade and eventually lost out to the Delta Shields. Let me know what you think about it if you run it.
