Anvil engineers will have a tough time using this ability as they are very slow units and preferably like to keep their distance with Vickers LMGs. So going Anvil with this commander is a bad idea.
Sapper rush is a viable strategy considering the flamethrowers unlock at 0CP and you can tech up almost immediately to unlock Sappers. Brits have always had issues clearing buildings vs. OKW so this will be perfect for maps like Angoville. Sten guns + flamethrowers, ouch.
CaptainSPrice engineer spam here we come.
Advanced Cover Combat
Absolutely devastating in critical defend-vp 1v1 situations. This can be tremendously useful. This ability can also be really good for Brit blobs so watch out. Also more incentive to make trenches.
Infiltration Commandos
Awesome sniper counter that Brits currently struggle with. Allies don't have infiltration units besides the mediocre Partisans, so this is actually a significant change. Axis players will have to be paranoid like Allies players are when placing support teams next to buildings. This may unfortunately make other Commando commanders obsolete :C
FINALLY A MORTAR/MG42/SNIPER counter besides the AEC.
Land Mattress
Possibly a good alternative to mortar pits. Also one of the only blob killers at the Brits disposal instead of the AVRE. Who wants more rocket artillery gais?


Counter Battery
Probably a counter-ability button in HQ. 25 lbers are inaccurate anyways, might as well keep them in counter barrage. The range is the whole map for 25 lbers.
Advanced assembly
Forward assembly spam. Repair station. Awesome, will be good for repairs for the team and as forward reinforcement places. Also good for simcity as they will be repairing emplacements. Emplacements already get a buff with the forward assembly nearby so this creates more incentive to do so.
Improved fortifications
A nice addition although I think stand fast may be a better alternative if you want invincible emplacements as stand fast pretty much increases HP of the emplacements. Interesting though, having an advanced forward assembly AND extra HP may be quite frustrating to counter.
*shivers*
Defensive Operations
Mortar pit rush. Interesting though... this will allow for interesting no-sapper builds. It's viable: instead of mines use munitions on killing HQs, you get repairs with forward assembly (lol forward assembly spam). So if repairs and munitions is taken care of, then aint nobody need any sappers

The Advanced Emplacement Regiment is a teamgame commander for the most part.
If anyone else has some new ideas/strats with these new commanders, feel free to post below!
