thought of this extremly dicky list40K Army: Imperial Guard
vets with carapace and plasma in chimera
vets with carapace and melta in chimera
3 hydra flaks
2 leman battles with 3 heavy bolters
1 leman demolisher with 2 multi meltas and a lascannon
spare 20p to spend on upgrades
what do you think? would this be considered competitive? or do I need more troops? I am new to powergaming!
