Ak's Random C:SM - The Sentinels of Terra

When I bought the The Sentinels of Terra, I just wanna know the rules and don't really think much about the fluff off these stubborn yellow fighters. But yesterday I was stuck at home taking care of the kids all by myself, so I opened up the PC and have a read. The fluff of the 3rd Company was very nice actually. Very different of what I expect from the Imperial Fist. It sparked interest in me to try the Sentinels and since I already have Lysander model, why not kan

So here it is, following the Crusade of Thunder roster:

3rd Company IF "Sentinels of Terra"
Lysander
3 Centurion Devastators Tynon| Gravcannon + Amp, Hurricane Bolters (250)
8 Tacticals Odan| Meltagun, CMelta+MBombs (137)

10 Tacticals Morix| Plasmaguns, CombiPlasma, Heavy Bolter (175)
- Rhino (35)
10 Tacticals Tannar| Plasmaguns, CombiPlasma, Heavy Bolter (175)
- Rhino (35)
5 Scouts Kord| 4 Snipers, 1 HBolter (Hellfire), Camo (82)

Storm Talon Sword of Polux | Skyhammer Missiles (125)
5 Devastators Tynon| 2 Lasscannons (110)
5 Devastators Connar| 2 Missiles Launchers (Flak) (120)
Thunderfire Cannon Terra's Roar(100)
ADL | Quadgun (100)
Total : 1849

They have Close Ranged Bolter Drill (reroll misses at half range with bolt weapons) and Tank Hunters (Devs+Cent only). Centurions Devs can be taken as Elite.

So how was it?
