Is there anything that indicates pre-clantech chemlasers were anywhere as effective? Because if they were, why the heck are people using mechs?
A current MCL is roughly equivalent to a clantech SRM4 on a vehicle. Tanks would outgun mechs so much it wouldn't be funny!
So using clantech it might be sort of reasonable to make chemical RE-lasers, VSPLs, or (standard) pulse lasers. IS tech, no way.
