Especially if you use some of the advanced LOS & sensor rules. without enough of the right forces both sides could stumble past each other without ever being spotted. If you build a map like a modern city that is larger than the 16x17 phonebook and use double blind. Urban combat tactics depends on the rules you are using and what you consider 'urban' terrain.

This gives a hover tank a +3 movement modifier and a +2 hull down position gives a + 5 total modifier but each tactic is only very strong type of urban planning set up. I could go on about gun emplacements or prepared hull down positions just outside the city that are 7 hexes apart. The militia on these worlds have to field units in huge numbers but can only send a tiny portion of it to intercept the enemy as the targets they have to defend a huge number of targets. Most planets seem to be the old everything centralized so it cannot efficiently be defended so objective raids have a good chance to work. Starting at the Second Succession War planning went toward better defenses and de centralized infrastructure. If it was built before or at the beginning of the Star League then the target world was planned for efficient production and distribution not defense. Urban defense in battletech revolves around how long ago the target area was built. A well defined defense in depth urban planning will most times will make them pay for every block taken. The BV of lightly armored concealed trailers puts a lot of offensive power. For more normal fights tanks and battle armor with TAG and Light TAG painting the enemy for homing, copperhead and semi-guided LRM and Mech Mortar rounds. If you are policing against mob units like those described in the Reunification War you use level one chemical weapons like tear gas and jump infantry with snipers with rubber bullets should break up the mob unit.
