A topic near and dear to my heart, as I'm on the tail end of 'tactical' but trying to hang on for a few years and keep up with the younger guys.
A couple of thoughts -
------------
I believe S&S makes an excellent military deployment workout, with a few simple additions (pullups, perhaps). I've not done a program that gave me gains and still left me feeling like I was fresh enough to go on an extended patrol at a moment's notice. I did a Crossfit workout in Afghanistan that left my back wrenched. That was the last time I did deadlifts for time. I remember laying in my cot hoping we didn't leave the FOB for a few days because I was in no condition to do anything. Even if I hadn't pulled my back, I would have been too smoked to be 100% for the next few days.
However, I don't think S&S is enough to prepare for a military selection. You are going to have to be more 'sport specific' with the 'sport' being the events of the selection.
------------
I think it helps to set some objective standards and goals, but this is not without pitfalls*.
Rippetoe has a decent set of military minimum standards that could also apply to LEOs
- Double bodyweight deadlift.
- Standing Overhead Press with 75% of bodyweight on the bar.
- Chin-ups-12 minimum
- 400 meters in 75 seconds or less.
Of course, Rip being Rip, he totally neglects long distance runs and rucks. But I think it's decent and can be attained by anyone with some time and effort. The standards aren't so high that you have to turn into a powerlifter to meet them.
---------------
I think it's good to make a distinction between urban LEOs and the military. For example, Tactical Barbell's conditioning book has 'green' and 'black' programs. Green being for military that needs long range movement capabilities and Black for LEOs that are not likely to patrol for days at a time or have long infils.

*So, Rips standards revolve mostly around a barbell. I discovered KBs relatively recently and I'm a sample of one. But I feel good when I work with kettlebells. My recent work with barbells has been a series of nagging to serious injuries, which may or may not have been related to using a barbell at 90% of my 1RM.
Everyone knows about the WTH effect, and I'm convinced there's something intrinsic with KBs that you won't appreciate if your standards revolve around the barbell. Eric Frohardt talked in a podcast about moving better when he switch to strictly KB work, and he had no drop off in PT scores from when he trained more specifically for the PT tests (or something like that). I'd probably hedge at this point and add deadlifts and pullups. If I'm being honest, there's probably no reason other than ego for me to bench press (aesthetics and to be able to answer "how much ya bench?" are not good reasons.)
