With the IG part of my vow reaching completion I set myself a deadline to finish them and included them in a list for a game on Sunday
Well it worked and I got them all finished on Saturday 

I thought the fluff behind the army would be some Imperial Guardsmen needing reinforcements to hold the line and some nearby Blood Angels coming in to save the day. Which is mostly how this game turned out, albeit with the Terminators coming in to win the game and steal the glory all by themselves 
Here you can see the paint scheme working as intended 

The brave Company Commander charges in to help the Scouts against the Tyranid menace:

The Brood Lord wipes out the accompanying IG squad (despite the Lord Commissar shooting one to try and make them stay) and so the Lord Commissar himself resolutely steps forward to continue the fight. The Commissariat practice what they preach:

The game ends here when my opponent calls it. The Blood Angels and Guard held the line long enough for the Terminator reinforcements to crush the enemy and save the day:

I then played a game against Chaos Marines which I lost but I didn't really take pictures myself. It actually went similar to this first game, although the Terminators didn't come in to save the day this time, and so the day went badly
I did learn a lot about Guardsmen though - mostly how they can't be relied upon to do much
However it's nice when now and then they get a wound or two on some big bad!
