It is very difficult in Enlisted to make snipers work well in your team, you need to either have a good position to pick targets directly out of the capture zone - or you manage to get a risky flank going and take out enemies before they manage to get to the point - which however will attract alot of attention, so you will need to be able to defend yourself in close range.
Also boltaction rifles require the most precision and quickest reaction times to make them work, which in general doesn’t sound ideal to new players or players with low FPS.
But in truth, they ARE useful, because of the wide choice of specialists you can bring in the squad. It can assault after a bombardment if you equip 2 assaulters. It can keep supporting from afar with a sniper. It can KEEP bombarding cap zones thanks to 2 engineers an their ammunition resupply. Or it can turn into a good cap defense squad with the same 2 engineers that build stuff.
Mortar squads, are versatile. Don’t underestimate them.
i find mortar most useful as first squad spawning and first cap is open cap. you can get loads of kills by firing on cap and around it. after that it is pretty meh if you are playing solo. sometimes you can get great results and sometimes it is pretty bad.
Unless you can continuously find dense enemies or key targets
Otherwise I don’t recommend hiding behind and using mortars for a long time
Make more use of smoke warheads
This has more tactical value than high-explosive bombs
The only tanks that light mortars can effectively attack are a few light tanks (the chance of destroying or igniting the engine is extremely low) and convertibles
Harassment with smoke grenades is more effective than ineffective attacks with high-explosive grenades
Unless you have a level 5 mortar, don’t try to attack a fully armored tank with high-explosive rounds.
Instead of just one assaulter, you can choose 2, as example, and BAM, you just got an extremely potent shock assault squad (mortar then charge). Riflemen as example, can only bring one type of specialist each: just one mg OR one assaulter OR one sniper…
Bonus:
Mortarmen squads, have the best uniforms. For Germany they are paratroopers so giving them fg42 feels justified. For Soviets with Berlin squads they were the only ones with blue nkvd caps, the Germany ss equivalent.
Maybe move the mortars and flamethrowers to other squads
For example, the communications group
Use smoke first and then attack with a flamethrower
this sounds great
