Something I use with some frequency is having my soldiers hit the ground and go prone. It's slower, yes, but if they do it while firing from behind a tree with a scientist close by to offer support, you can really dish out some damage and take less yourself. Sometimes two medics can heal the wounded unit as fast as he's taking damage. I always take two scientists with my squad of soldiers, so they can heal each other if need be. Otherwise, if your one scientist is wounded badly all your soldiers will do is watch him bleed to death.
I love firing from the higher ground. It really improves your firing distance and some hills are very hard to reach or downright impossible on a vehicle.
Stealing enemy vehicles is quite productive. Sometimes you end up with a rig you can't even build yet and it takes less time to steal than build.
"Stealing" buildings is also pretty good. If you're raiding a base, you can try to have an engineer tag along, though they're easy to kill, so be very careful. Still, taking a building for yourself takes less time than destroying it, depending on how many troops are doing the attack.
Training apemen can be a hassle, but once you got a couple, they're always helpful for mundane tasks like resource gathering and helping build bases faster. In a pinch, like a random enemy soldier attacking your helpless base, you can always throw them at the enemy. Cold, I know, but they're the only expendable living units in the game. They don't level, there's no unit limit on missions (build more farms!) that I know of or morale loss for losing troops (except your own when you look at that gray, somber, portrait staring right back at you and wondering why... WHY!?), so spending some time training apemen (on non-timer missions) can be useful.
Cannons and lasers are good against vehicles and buildings, but not as good against people, machine guns and Gatling guns are good against people but not as good against vehicles. Use that to your advantage and their disadvantage.
The game itself is not really that difficult. It's NOT LOSING MEN what makes it difficult. :-)
Oh, minor last note. An apeman flashing up on your screen and going UGH! UGH! does not mean he's bored and wants to play poker. Apemen don't complain from boredom. Ugh Ugh! means "Crates here!" in Apeish.
