3/28 update: Updated to official EN translations.
AT4 is an anti-tank missile like BGM-71, and functions similarly. Her most important stats are Lethality and Pierce, and she prioritizes enemies with the most Shielding.
Participating in Theater #1 will award players AT4 Central Data, with more accumulated points corresponding to more copies.
The high Pierce stat of AT4 makes her work well for breaking enemy Force Shields, and her skills that scale off Lethality allow AT4 to perform as a better all-rounder than BGM-71 due to some of her Pierce budget being reallocated to direct damage. Her lower range of 2 tiles gives her much of the same limitations as BGM-71 when fielded on maps.
AT4 does well when both a moderate amount of Pierce and direct damage are needed, but due to the nature of her as a reward HOC, players may not have her at as high of a rarity as BGM-71 and thus would prefer BGM-71 anyway.

Should I use Data Patches to iterate this HOC?

Full Analysis
AT4 comes second to BGM-71 as an excellent HOC for hard countering enemy Force Shields, and should be raised to level 40 then 60 (as soon as the player finishes upgrading the Training Range to Level 10) so that AT4 can equip 5★ Chips to raise her two most important stats, Pierce and Lethality.
- This requires x209 and x836 respectively. The Black Market sells x600 each month, so there should be plenty to let her reach Level 60 fairly soon.
- Blue Chips with high Lethality should be given to AT4 first, as she scales off the Lethality stat much better than BGM-71 does.
Her normal attack deals 1.5x Lethality and 1x Pierce to the main target, as well as 0.5x Lethality and 1x Pierce to enemies within a 1.5 radius AoE.
Because most enemies have shields that would be one-shot anyway by AT4 despite her lower Pierce value, she's a perfectly fine substitute for BGM-71 in most scenarios (note that some particularly tough enemies will have very high shield values that necessitate the deployment of BGM-71 to reduce them in time). Once players manage to raise AT4 to 5★ rarity (not possible with Theatre rewards alone), she can perform better in certain situations due to her higher upfront damage. Until then, BGM-71 will remain generally preferred by most players who played since the HOC feature launch due to the head-start she has in rarity and skill training.

This is the skill that differentiates AT4 from BGM-71; instead of
more Pierce, she deals direct damage scaling with her Lethality.
The multiplier is much better her other skills and the proc chance is not 100% until it's fully maxed, so Skill 1 should be prioritized. |

This is a fairly useful debuff, but the return on investment is not
very high. This can be leveled with a relatively lower priority.

Intensive Burning adds a respectable amount of damage-over-time to
AT4's overall DPS, and should be leveled after Impact Sputter.

Players should prioritize Chips with high Lethality and Pierce when equipping AT4.
- Having a high amount of Pierce is important to let AT4 break force shields effectively, even though all of her skills scale based off of Lethality.
After Pierce is maxed or nearly maxed, investing in Lethality is recommended to let AT4 effectively differentiate herself from BGM-71.
While Precision and Reload are less important, they can be increased if the player is able to do so with minimal opportunity cost.
Swap out pieces for the Same Color Bonus only when it results in a net increase of stats.
Since the player will be rearranging the Circuit Board each time AT4 increases in rarity, it's not necessary to rotate (calibrate) Chips until she reaches 5★ rarity. BGM-71 should get the chips with a lot of Pierce while AT4 should get the chips that have a lot of both Pierce and Lethality. It is nevertheless relatively safe to enhance Chips (even low rarity chips) so long as the enhancement fodder is of the same color, since you can simply feed your enhanced chips to better chips and have most of the stored EXP (80% of its accumulated EXP) carry over.
Note that in particularly challenging fights, AT4's shield break will be insufficient by herself; it is recommended to bring BGM-71 for those battles.

Trivia
The AT4 (also AT-4) is a Swedish unguided anti-tank missile produced by Saab Bofors Dynamics - the same manufacturer of C-MS. It's a huge commercial success and is one of the most widely used anti-tank weapons today.
- AT4's operators are differentiated by their hair accessory as well as differently-colored ribbons.
- Their uniform is themed after the Flag of Sweden.
